KNOWN BUGS AND RESTRICTONS IN SCRIPTX VERSION 1.5 This document contains up-to-date information about the known bugs and restrictions in Version 1.5 of ScriptX. These restrictions are divided into components which are listed in alphabetical order. Each bug report contains the bug number, a description, and possibly a workaround. The components included are as follows: 2D Graphics Loadables - Transitions Animation Loadables - xcmd Clocks Loader Collections Memory Management Config - Audio Modules Config - General Numerics Config - Video Object Store Controllers Object System Kernel Document Templates Players - Interleaved Environment Players - Video Events Presenters Exceptions Printing Files - DirReps Spaces Importers - ART Streams Importers - DIB Tethered Editors Importers - General Text & Fonts Importers - PICT Threads Importers - QuickTime Title Management Importers - RTF Tools - Browsers Importers - WAVE Tools - Debug Tools KMP App Tools - Widgets Language Transitions Language - General User Interface Language - ScriptX Visual Memory ______________________________________________________ 2D Graphics 3458 Macintosh only: When the remapOnDraw instance variable of a bitmap is set to true and the bitmap is rendered, the bitmap's colormap does not get remapped to the colormap of the surface. 3525 Windows only: In rotating a bitmap, it may distort as well as rotate. 3628 The vertical display coordinate origins are not compatible across platforms. For example, when you specify a y-position of 40 on the Macintosh, your window is right below the system menu bar. On Windows, there is a sizable gap. 3703 The arc method does not draw a perfect arc. The radius is slightly different at different points. 3704 When drawing a complete circle, arc and arcn produce different outputs. arc mistakenly produces a circle that is completely closed, while arcn produces a circle with a slight opening, as is expected. 3709 Setting the brush lineWidth to 0 does not draw using the smallest line width possible, as it states in Class Reference. 3714 Macintosh only: In performing a transform on a bitmap, and appending it to a LibraryContainer, the color of the matte changes, while the color value of the matteColor instance variable does not change. 3758 Different results are produced depending on when a transformation matrix is applied to a BitmapSurface. If you apply theMatrix when you fill the bitmapsurface and then call transform with an identityMatrix, the resulting image shows some banding. However, if you apply the identityMatrix when you fill the bitmapsurface and then transform it with theMatrix, the image looks fine. Workaround: Apply the identityMatrix when you fill the bitmapsurface and then transform it with theMatrix. 3850 GroupPresenters are not stroked correctly. For example, bounding boxes are stroked, not the union of their boundaries. 3869 Animating a Line object fills memory with Line objects that are not collected, thus generating garbage. Workaround: use a Path object instead of a line. 3876 White areas may be shown when a bitmap is rotated in some situations. 3890 Rotating a bitmap gradually degrades the image. Workaround: Instead of rotating an image, rotate a matrix and apply it to the original image. The image does not degrade. 3900 TwoDMultiPresenter clips at its bounding box (bbox) rather than its boundary. 3923 The onBoundary method for Stencil returns true only when the coordinates passed represent the corner of the bounding box of the Stencil. 3927 The remapOnSet instance variable defined by Bitmap is a no-op on both Macintosh and Windows. In addition, using the colormap: keyword while importing a bitmap does not work on Windows, although it does work on the Macintosh. Workaround: Write to a bitmap surface at runtime to set the colormap dynamically, and then convert the result back to a bitmap. 3952 Windows only: GDI resources are not freed when you using a user defined pattern for a brush object. 3975 TwoDSpace uses the rectangular bbounding base (bbase) as its clipping region instead of using its boundary as a clippings region. The result is that if you add a presenter such as a TwoDShape to a space whose boundary is, for example, an oval, you see that the presenter is clipped by the rectangluar area surrounding the oval, instead of by the oval. 4105 If a TwoDShape object uses a bitmap stored in a library container, with the invisibleColor of the bitmap set and the shape appended to a window stored in a title Container, the invisibleColor of the bitmap fails. The shape appears in the window with its rectangular boundary. 4178 Windows only: One gray color in the default color palette appears yellow. 4198 Bitmaps are skewed or rotated 45 degrees or so when displayed in Win95. The bitmap of values, such as 2, 6, 10, where the value is divisible by 2 but not by 4, will appear skewed. 4199 Windows only: Shapes created from paths can be rotated but shapes created from imported bitmaps disappear when rotated. 4200 Windows only: Setting the invisibe color for bitmap does not work on Windows. It works on the Macintosh. _______________________________________________________ Animation 3247 Windows only: If an animation is temporarily interrupted, when the animation continues, the animation moves in fast motion as if it were trying to catch up. 3474 ActionListPlayer does not play in reverse. 3534 In the TimeAction class, the time instance variable cannot be set after the action has been created. The time action will not occur. Workaround: Add the keyword time when creating the TimeAction instance, setting its value to the end of the list. For example: global t10 := new TimeAction targetNum:0 destTime:5 time:10. ___________________________________________________________ Clocks 3617 Calls to set the value of the authorData and target instance variables on callbacks are ignored. Therefore, a callback cannot be easily modified once it has been created. 3670 New clocks that are added to a paused title are not paused. 4083 Referencing the date instance variable of theCalendarClock triggers periodic callbacks on that clock, if you addded any to it. _____________________________________________________________ Collections 3050 The expression for i in 1 to 6 collect by append i returns the NoMethod exception. Workaround: This is not actually a bug. Only collection methods that return a collection are suppsed to be in the by cause. Do not use append; use the global function appendReturningSelf. See the discussion of the for expression in the ScriptX Language Guide and also the definition of the appendReturningSelf in the global function section of the Class Reference. You can also use an anonymous function to create a wrapper for append that returns the collection rather than the appended key. 3072 Calling seekFromStart beyond End of File (EOF) on SequenceIterator reports an exception. 3075 Nearly all iterators return incorrect results for (seekFromEnd iter 0). 3107 The method stringOf on ByteString, String, Name, and Exception is available from the scripter, although it is not documented. 3327 The remainder method on KeyedLinkedListIterator returns a collection of value:value pairs rather than a collection of key:value pairs. 3395 When coercing a string to NameClass, the case may change unexpectedly. Workaround: This is not a bug. NameClass objects are not case sensitive. 3476 In collections, when defining a range using floats, and attempting to increment by a fraction, an incorrect value is returned. 3513 The classes Single, Pair, Triple, and Quad do not specialize the addToContents method, which is hidden from the scripter. As a result, it is not possible to use the object syntax in the ScriptX language to set the values for members of these bounded collections. 3592 The keyword initialSize in ByteString is off by one less than specified. 3711 ScriptX crashes when creating a new instance of a subclass of Sequence. 4031 For IndirectCollection, deleteKeyOne calls objectRemoved with the key, not the value, and this causes objectRemoved to be called with incorrect arguments. 4192 The eq operator returns a different value from equal. ____________________________________________________________ Config - Audio 3420 PS/2 only: ScriptX causes a fatal system crash if system sounds are enabled and a sound is played. Workaround: Turn off system sounds. 3832 IBM microchannel M-Audio card fails to produce sound. _____________________________________________________________ Config - General 3974 Windows only: Cannot launch ScriptX or the KMP from CD- ROM on an IBM ThinkPad. _______________________________________________________________ Config - Video 3273 The QVision video card may experience poor performance. ____________________________________________________ Controllers 3769 You are not prevented from creating instances of many abstract classes, even though those instances are incomplete and therefore useless. 4189 If an object is controlled by a bounce controller, the object goes past an edge it encounters. ____________________________________________________ Document Templates 2965 localEqual fails when comparing two Page objects of the same value. 3003 Page objects do not compare correctly. equal returns false when it should return true. The same applies to PageElement and PageTemplate. 3005 A PageElement object acts as a proxy for its target. This can result in seemingly illogical behavior. For example, isAKindOf on an instance of PageElement returns true for TextPresenter, if a TextPresenter object is the target of the PageElement object, while TextPresenter does not show up in the list returned from getSupers on the PageElement class. 4197 System crashes when you try to add custom instance variables in the definition of a PageElement object. ____________________________________________________ Environment 3182 Windows only: ScriptX fails to run on the Japanese version of Windows 3.1 3200 When a script has been filed-in without -<<< ->>> requiring one to hit the Return button after each line 3204 The default state for a newly created MDTextWindow is visible on Windows and hidden on the Macintosh. 3509 Windows only: When trying to open a file that does not have an extension, ScriptX will not read in the file. 3598 Windows only: When the splash screen initially comes up there is a thick blue border around it that does not exist on the Macintosh. 3961 Windows Only: Command-delete in Listener does not delete all text from cursor to end. 3985 On the Macintosh, copying a new version of ScriptX onto your local drive sometimes causes drag-and-drop to fail. Workaround: Rebuild the desktop. 4001 ScriptX will not boot on PowerMac without installing QuickTime. Workaround: Install QuickTime to boot ScriptX on PowerMac. 4201 Command line arguments to ScriptX must now include a fully qualified path. Workaround: Install QuickTime to boot ScriptX on PowerMac. _________________________________________________________________ Events 3622 Macintosh only: On compact Macs without a numeric keypad, like a PowerBook, the Enter key is not mapped. 4005 hasUserFocus on the Window class can be set to true before the window is visible, which may prevent forceFocus from working. 4122 When executing a startupAction that calls signal on an event that has been stored in a title container, an exception will occur. __________________________________________________________________ Exceptions 3024 If the WIDGETS.SXL file is missing but tools are being loaded, a dialog will notify you of a problem, offering Quit and Continue options. If Continue is chosen, ScriptX crashes with a bus error. Workaround: If this dialog appears, choose Quit and load tools with the WIDGETS.SXL file in place. ___________________________________________________________________ Files - DirReps 3219 Windows only: Creating a file with no given extension reports an error. Workaround: Provide an extension when creating a file. 3257 Macintosh only: The fixNameForOS method returns bad strings when passed a long filename. 3554 Macintosh only: The createFile method should throw an exception when creating a file on a read-only diskette, but it does not. A string of the filename is returned, even when the file is not created on the diskette. 4067 Open title will fail on files on a network drive. ____________________________________________________ Importers - ART 3903 Setting mattecolor and invisiblecolor on KIC compressed images might not change the color. ____________________________________________________ Importers - DIB 3084 Macintosh only: When you import a 24-bit DIB using the DIB importer with @compressedBitmap as the output media type, the results are incorrect. 3560 Importing the colormap of a 24-bit uncompressed BMP file returns an error. 4143 Macintosh only: Importing a 24-bit uncompressed bitmap does not work. ____________________________________________________ Importers - General 3759 The QuickTime-to-Bitmap importer fails to import for a QuickTime movie that has all key frames. It states, Frame beyond the end of the movie. ____________________________________________________ Importers - PICT 3956 Windows only: importing a pict file twice without resetting the cursor on the stream generates a read error message. 4142 Windows only: pict importer makes system hang when importing a 24-bit pict. ____________________________________________________ Importers - QuickTime 3058 When presented with a movie that has multiple sound descriptions, the QuickTime importer crashes with a bus errors. ____________________________________________________ Importers - RTF 3393 Importing an RTF file that has a header or a footer, and displaying the imported text in ScriptX, causes ScriptX to freeze. This may require rebooting. Workaround: Do not import an RTF file that contains a header or a footer for display in ScriptX. This bug may be fixed. ____________________________________________________ Importers - WAVE 3864 Imported 44Khz 16-bit WAVE audio plays at too low a pitch on the Macintosh. Workaround: Change the DigitalAudioPlayer pitch instance variable from 60 to 84. __________________________________________________________________ KMP App 3799 On the Macintosh, file type and file extension are determined by Macintosh-specific elements of a file, with creator fields that cannot be included in cross-platform distributions. Workaround: Macintosh only: Allow files with the proper file extensions (.sxt, .sxl, .sxa) to be opened by the Kaleida Media Player even if the file type and creator fields are not set correctly. ___________________________________________________________________ Language 2996 The following classes do not behave correctly with copy on a subclass: Bitmap, BitmapCompressionInfo, Brush, ClippedStencil, ColorMap, Line, MdByteString, Oval, Path, RGBColor, Rect, Region, RoundRect, StringConstant, TextPresenter, VideoFrameDesc, Window. Workaround: See the discussion of copying objects in the "Object System Kernel" chapter of the Componenets Guide. 3039 getLowercase "\<10000>" causes ScriptX to crash with a fatal error. Workaround: Use no more than 4 digits with getLowercase "\<NNNN>". 3046 Calling any of the following on instances can cause crashes: init, afterInit, afterLoading, initCopy, inflate. Workaround: Do not do it. These methods are visible so that they can be specialized. They are not meant to be called from the scripter. 3052 localEqual compares two collections, item by item, to determine if their members are locally equal. If collections contain other collections embedded within, then localEqual causes ScriptX to crash. 3102 In the Browser, when browsing a core class, the list of methods does not match the result of getDirectMethods. 3539 In the loadable transitions, when a loadable class is referenced prior to having loaded the class, it is not recognized after the class is loaded. Workaround: Always make sure loadable transtions are loaded before referencing them. 3673 Variable modifier initializer does not function properly. Workaround: Although defined in the ScriptX syntax, scripted initializers have not yet been implemented in version 1.5. Implement initialization by specializing afterLoading. 3692 ScriptX crashes without reporting an exception when trying to redefine a constant. __________________________________________________________ Language - ScriptX 3782 A syntax error is reported if a line break occurs immediately after a function fnName definition begins. However, the parser does not report an error if the line break occurs after function fnName firstArg or function fnName ->. Workaround: Do not break a line after the name in a function definition. 4182 A small memory leak might occur when coercing arguments passed into a function into string objects and then coercing those string objects into NameClass objects. Workaround: In this situation, use the new syntax to create the NameClass object, rather than coercing the string object into a NameClass object. ___________________________________________________________ Loadables - General 4208 If you create a subclass of a loadable class, such as QuickTimePlayer or one of the widget classes, such as TextButton, that subclass will not be stored. Therefore, at runtime it will not be present. Workaround: Subclass the loadable class at runtime, which you can do in the startupAction method. ___________________________________________________________ Loadables - Transitions 3924 Dissolve transitions do not work properly. ___________________________________________________________ Loadables - xcmd 3918 Loadable XCMD is not functional. Attempting to load the XCMD reports various LoaderHelper errors. ___________________________________________________________ Loader 3643 relinquish method does not call exit within a function in a loadable unit. ___________________________________________________________ Memory Management 3694 ScriptX crashes when it is set to start up with insufficient memory. ___________________________________________________________ Modules 3669 When multiple modules are stored in a single title container, the modules must be explicitly de-referenced via the load method at startup time. Simply setting a variable equal to the module’s proxy is not enough to load all defined variables. 3718 When a module is redefined, renames does not work properly. 4004 Redefining a module variable after storing it to a container, then reloading the objects, causes ScriptX to crash. ___________________________________________________________ Numerics 3612 Matrix operations lead to a value of 1 (ImmediateInteger) on Windows but 1.0000 (Float) on Macintosh. Note that this can cause cross-platform compatibility problems. 3618 A date earlier than 1970 cannot be entered. Workaround: Enter a date after 1970. 3654 posInf cannot be used as the upper boundary in a NumberRange object. 3802 When making a copy of a Date instance, the same Date object is returned. 3868 Allocating objects during a performance critical animation may reduce frame rate. 4019 A computation on an undefined number returns an invalid number. 4021 Windows only: When attempting to initialize a date with the day set to anything greater than 28, the hour is set to 1 hour less than the actual hour. 4089 The addMonths instance method malfunctions. Workaround: Use alternate method to calculate date. ___________________________________________________________ Object Store 2982 The directory instance variable of a library is not set when the library is opened implicitly by a title. 3144 LibraryContainers objects and subclasses do not call preStartupAction before trying to load the libraries on which they depend. 3544 Windows only: In Tools, placing the sxd folder in the Tools folder will cause ScriptX to crash on launch. Workaround: Place the widget library in theStartDir folder (outside the tools folder). When the widget library is in the tools folder, it is loaded once by the tools loader after being loaded implicilty by a tool. 3734 If a container is initially opened read-only, then it cannot be updated during that ScriptX session, even if you close the container and re-open it in Update mode. 3795 Using update myContainer creates containers that are 45MB on the PC platform and 13 MB on the Macintosh platform, instead of 1MB in size. Workaround: Since update myContainer is writing everything to the storage system, do not use update myContainer in a loop where items are added to the target collection. 3885 Caution: If you have a container (A) that uses a object1 that is stored in another container (B), but is not listed in container B's targetCollection instance variable, when a new class is added to container B in front of object1, container A's reference to object1 may be incorrect. 3986 Containers opened in default read-only mode are sometimes updated on close. 3990 ScriptX crashes upon opening a library container in @update mode and adding a new object to the library container. 4207 Windows only: A check for whether a container is already open assumes a case-sensitive uppercase filename. As a result, a container is opened twice, causing a <module> cannot be redefined error. On both Windows and Macintosh, file Open is case-insensitive, so there is no method to detect in which case a file might have been originally opened. This is a problem for cross-container applications. Workaround: Type container filenames in lowercase before comparing or perform a case insensitive container name comparison. ___________________________________________________________ Object System Kernel 3286 Recompiling a class that has instances does not properly report an exception on either the Macintosh or Windows platform. Both respond differently and incorrectly. 3305 Class and instance variables declared transient are returned from the object store as non-objects, when attempting to retrieve them from a container. Workaround: Since scupled initializer functions have not been implemented yet in the current version of ScriptX, specialize afterLoading to set the initial value of a transient variable. 3456 Using map with the global function eq returns non-objects. 3457 Using map and the numerics method sum reports an exception. 3520 The allInstances generic function can consume a lot of memory, if called repeatedly. 3787 The garbagecollect() function causes ScriptX to crash upon freeing a specialized class. Workaround: It is not recommended to override deflate and inflateInstance class methods. ___________________________________________________________ Players -Interleaved 4214 If SpeedDoubler is installed and Speed Access, a component of SpeedDoubler that does better CD caching, is running, movie playback performance off the CD is sub-standard. ___________________________________________________________ Players - Video 3049 Invisible color instance variable does not work when a palette changes in a video player, even if the palette is returned. to the same mode. 3057 You cannot interrupt or type in the Listener while playing video from a compact disc (CD) at negative rates, even after the video finishes. 3421 When you change the target of a movie player, the movie player does not stop its current slave clocks. The previous movie keeps playing and you may get a long delay when you start playing a new movie. Workaround: Stop the movie player before changing its target. 3492 Macintosh only: The audio goes away when the window containing a QuickTime player is hidden. 3514 Windows only: When the window containing a VFWPlayer (Video for Windows player) is shown, it gets shifted 2-3 pixels up and to the left. ___________________________________________________________ Presenters 3322 Transform matrices and direct presenters do not interact correctly. The boundary is ignored when rendering direct presenters. 3414 When a TwoDMultipresenter object is transformed, such as scaled or rotated, its subpresenters do not get transformed. Workaround: Explicitly transform the subpresenters of the TwoDMultiPresenter object. Make sure to take the origin of each subpresenter into account. 4165 A newly created window displays garbage at the bottom, if the width is set before setting a height that is over 400. Workaround: Set width after height when height is over 400. ___________________________________________________________ Printing 3700 he paperBoundary for an instance of PrinterSpace or PrinterSurface can be changed, but it should not be able to be changed. Also, the boundary for PrinterSurface can be changed, but it should not be able to be altered. Workaround: Do not change the paperBoundary for an instance of PrinterSpace or PrinterSurface. Also, do not change the boundary for PrinterSurface. 3701 If the fill color is set to whiteColor, and a selected PostScript printer is set to black-and-white mode, a rectangle prints solid black. 4103 Windows only: Printing a DocTemplate application returns an error. When printing a large region, GDI memory may run low and not print. ___________________________________________________________ Spaces 3471 When an object is appended to a GroupPresenter, its rectangular bounding box is stroked, rather than the object itself. 3671 If a space's clock is running while the space is being saved to the object store, the objects contained by the space may be saved with inconsistent state. Workaround: Pause and restore the spaces so that items are saved and restored away in a state you expect. 3685 If you open an accessory or title container that does not create windows, ScriptX incorrectly clears the hasUserFocus of the existing top level title container window, unless focus has been explicitly switched away from and back to that top level window. When hasUserFocus has been cleared, it is impossible for an accessory to discover which title container has user focus. 3748 Hiding a direct presenter does not cause it to disappear from the window. Workaround: Set the direct presenter instance variable to false before hiding the presenter. 3791 Macintosh Only: PaletteWindow is unable to detect mouse- down events in a 15 x 15 pixel square in the lower right-hand corner. 3993 Calling appendNew on an instance of TwoDMultipresenter reports an exception. 4174 findAllAtPoint, and perhaps the related TwoDMultiPresenter methods, do not work. The findAllAtPoint method appears to be checking for an overlap between the query point and the local boundary of the presenters, instead of checking the boundary of the presenters after the globalTransform is applied. ___________________________________________________________ Streams 3161 In the ByteStream class, the pipePartial method is missing the last character of bytestrings. 3196 A copy of a mdByteString is always growable, even when the original is not. 4086 frameRate iv in VideoStream is supposed to be read-only. Currently you can assign a value to it without getting an exception. ___________________________________________________________ Tethered Editors 4144 When executing Send Script in BBEdit version 3.5, hitting Cancel in the "Select the ScriptX app" box can cause BBEdit to crash. ___________________________________________________________ Text & Fonts 2976 Setting a text's selection to a backward range (10 to 6 by -1) draws the highlighting incorrectly. The range should be selected with the cursor at the beginning. When dragging to select text, the cursor stays at the end of the selection. It should follow the mouse and end up at the position where the mouse is released. 3293 Platform-specific characters prevent transfer from the system clipboard. There is no way to get at the system clipboard as anything other than Text — as a byte array, for example. 3515 When a title is built on the Macintosh and moved to Windows, the Courier New and Wingdings fonts do not work. If rebuilt on Windows, all fonts work correctly. 3523 When the target of a TextPresenter extends beyond the width of the presenter, the entire word is not shown. Workaround: Increase width of textPresenter or reduce length of word in target. 3533 Importing very large text causes the thread to overflow its stack. Workaround: There is a limitation of about 100 operands in a single expression. So, for example, having over a hundred strings joined together with the plus operator does not work. You can avoid this problem by just having one string. In ScriptX, a string can extend over the end of a line and be as long as you like. 3541 TextPresenter does not take the inset of the text into account when detecting a hot region for performing actions. The active mouse area is off by the inset amount. 3687 Macintosh only: Font type and size of the menu bar and window title bars can be mistakenly changed by a sequence of commands issued from a script or in the listener window, when theTitleContainer.systemMenuBar is hidden. 3848 setAttr does not set the color correctly when the end of the range is not at the end of the text. 3867 Text presenters generate garbage when drawing. 3873 The event interest instance variables of TextEdit are not accessible through ScriptX and enabledSetter is not specialized to remove and add events. If you attempt to run through the eventInterests instance variables to implement TextEdit disabling, and if the TextEdit had focus in its window, it will re-add the keyInterest event when focus is restored to the window. Workaround: Use with extreme caution, since this relies on information that is subject to change. Disable a TextEdit box so that it does not receive KeyboardDownEvents. 3914 Coercing a NameClass object to a string constant throws an error. In addition, coercing a NameClass object to a Text object mistakenly includes the @ sign. Workaround: Coerce the NameClass object to a String object adn the to a StringConstant object or a Text object. 4117 Text color changes to black from white when a window is moved to a second monitor that is set to a different color resolution. 4193 If you call calculate on a text presenter that has an empty string as its target, it throws an exception "No undefined instance method for Substrate:UndefinedClass." Workaround: Assign any string (such as a space) with a length greater than zero to the target. Then calculate will work. ___________________________________________________________ Threads 3451 Calling threadProtect on threads whose staus is @inactive or @done does not change the protection level of the thread. 3589 A quit query function must run in a separate thread. It is does not work to present a dialog box asking Okay to quit? Y/N. After the box appears, one must block the thread to prevent the quit query function from continuing, to allow the user to press Yes or No. But in blocking the current thread, all events are blocked, because the quit query function runs in the thread labeled EventDispatchQueue—it should instead run in another thread. It works to type quit() in the Listener. However, if you type Command-Q or choose Quit from the File menu, the dialog box appears but the pushbuttons do not respond to user input. Workaround: Create a separate thread to run the quit query function. ___________________________________________________________ Title Management 3269 Opening a LibraryContainer instance is inconsistent between the open method and opening it from the file menu. Opening from the file menu creates a new DirRep representing the full path to the container file, and assigns this DirRep to the directory instance variable. This DirRep is also appended to theContainerSearchList global variable. Opening with the open method does not generate a new DirRep, nor does it append a DirRep to theContainerSearchList. 3300 ScriptX retains a reference via filename for each created or opened LibraryContainer instance. A new LibraryContainer instance cannot be created with the existing filename until after ScriptX quits. Workaround: After building library containers, quit and restart ScriptX. 3301 If you open a LibraryContainer more than once during a ScriptX session, terminateAction is called only the first time you close it. Workaround: Do not use terminateAction; try to write your code to not rely on terminateAction. 3506 If a title container is opened, and then closed using CloseTitle from the File menu, and then re-opened from the File menu, the file will be reported as "In use." The file cannot be opened a second time from the File menu. Workaround: Titles can be opened and closed as often as you want programmatically. 3626 The directory instance variable is not set at preStartUpAction, where it is needed for adding paths to theContainerSearchList. 3722 Extra windows show up in the Scratch title container windows instance variable. This happens because placing a presenter in a storage container saves the entire presentation hierarchy it is in. 3839 ScriptX does not keep track of the pointer (cursor) when you switch between titles. In other words, if title a is running and you change the cursor to wait, you switch to title b, but the cursor stays wait even though b's cursor should be a pointer. 3855 Setting the colormap of a Window object has no effect if the window is hidden. 4006 The version instance variable of a LibraryContainer instance returns a non-object, if left unassigned. It should return undefined. 4092 Classes returned by the getAccessory method of the accessory container are not getting loaded. 4110 The Systemmenubar is inconsistent across platforms. On the Macintosh the Systemmenu comes up with Print disabled, which is correct, while on Windows it is enabled. 4112 The topPlayers instance variable is not being set after a title container is opened. 4113 A window created during the startupAction of a title container has its title instance variable set to theScratchTitle instead of to the title container that created it. Workaround: When creating a window in the startup action, set the window's title keyword to the appropriate title container. 4185 Do not set the height of a Window object by using the boundary instance variable. Workaround: Use the height instance variable instead. 4205 theOpenContainers displays duplicate containers if open was called on the same container twice. ___________________________________________________________ Tools - Debug Tools 4132 If you try to Step Into or Step Over calls to waitTime, the Debugger often takes control and does not give it back. You have to quit ScriptX. 4163 When specifying a breakpoint for a function in a module, you must specify the module name—modulename: fn or classname^methodname. 4168 The browser menu is loaded twice. Selecting browser menu item ob-1 in ScriptX tools menu will create two identical browser menus. ___________________________________________________________ Tools - Widgets 4073 In PopupMenu widgets, a value of 0 or "nothing selected" cannot be specified. If you mouseUp and the mouse is not over the menu area, no selection is indicated. The last highlighted item, however, is the value returned, regardless of whether the mouseUp occurred inside or outside the menu. 4135 If you create a scrollListBox with a height value too small to fit in the scroll bar, the scroll box fits only partially in between the up and down arrows. Thus, when scrolling up and down, the scroll box overlaps the up or down arrow, depending on the position in the list box. 4136 If text is longer than the size of the text area in popupMenu, the text overlaps with the down arrow icon. 4138 When label text in radio button group is too long to fit in the text area, the text should be cut off one character before the right border line. Instead, the text runs over the edge of the box. 4139 If you create a multilinelistbox specifying a certain boundary value, and before appending the list box to the window, you resize it with a new boundary that is wider than it had been previously set, list box is drawn incorrectly. The original list box is filled with a white backgournd, while the area added after the boundary was enlarged remains gray. 4162 Assigning a new font for a widgets object does not set the font unless notifyChanged is used. Workaround: Set font for widgets and call notifyChanged. 4190 The ScrollingTextEdit example in wdgtest.sx is not working. Scrolling is never enabled. Any text you type in past the bottom of the visible boundary remains invisible for all time. ___________________________________________________________ Transitions 3034 In Transitions, when transitioning a shape whose boundary is a clipped Stencil, the transition occurs over the clipped region as well. 3267 When transitioning a TextPresenter within a OneOfNPresenter, the text displays itself for an instant and then goes away before transitioning. Workaround: If the targetSelector is not used, the flicker does not occur. 3272 In Transitions, if the duration is set to zero, an expected error is not reported. 3447 In transition players, when the duration is set to a large integer and the scale is set to a large integer, the transition flickers. 3475 In the Loadable Transitions, the Dissolve class’s invisibleColor instance variable has no effect. The white background matte is still visible. 3497 In the Loadable Transitions, the Dissolve effect, which is a special transition class that freezes the clocks, disregards the duration setting. 3749 Dissolve transition does not work correctly when the transition player is moved in x or y. 3896 Windows only: The instance variable autoSplice defined by the TransitionPlayer class does not function properly. 3897 The instance variable cachedTarget.data defined by the TransitionPlayer class does not return the same result across platforms. 3901 The following transitions do not play at consistent rates: Checkerboard, Fan, Iris, rectIris, StripSlide, Wipe. 3904 Windows only: Getting an instance of a transition, with useOffscreen set to true, does not work when the target is a QuickTime movie. 4065 Windows only: The iris transition does not work for calliope. The transition, when used, never presents an iris 'look.' It just changes from one space completely to the other. 4181 Windows only: Invisible color on the bitmap surface, cachedTarget, is not rendered during a Wipe transition. ___________________________________________________________ User Interface 2961 When attempting to instantiate a class that inherits from both TextPresenter and Pushbutton, an error message appears. 3498 Macintosh only: The origin of a notice window and a dialog window is not in the top left corner of the window. It is offset slightly inward. 3970 With the new Scrollbar, clicking on the track moves the thumb more than one page. It is sensitive to holding down the mouse button. In the old Scrollbar, when the mouse button is held down there is a delay, which disappeared in the new scrollbar. Therefore, a click will produce from two to five times the scrolling specified in the pageAmount. 4082 Usage note: When you specify the size of a resizable window on the Windows platform, the client area is less than you want because of the resize bars. The boundary of the window should be the client area, the physical window should be bigger. 4156 Enabling an ActuatorController instance twice throws an exception. Workaround: Check the value of enabled before setting a new value. 4188 When watching the mouse crossing events, if the presenter's coordinates of x or y = 0, and it is against the border or titlebar of a window, the MouseCrossingEvent @enter event occurs but not the MouseCrossingEvent @leave event. ___________________________________________________________ Visual Memory 3922 The Visual Memory window leaves trails when it is moved during an animation.
