EDGE Diagrammer relies on a file called THREED.VBX made by Sheridan Software to provide some simple dialog box controls such as the percent progress box. Some versions of THREED.VBX contained a backwards incompatibility for Visual C++ applications such as EDGE Diagrammer. If you install EDGE Diagrammer when you already have an incompatible (newer) version of THREED.VBX on your system, the result can be bad. For example, EDGE Diagrammer can crash (GPF) when you enter a style dialog box, or double click on a figure, convert a diagram, or print a diagram. V1.0 required: THREED.VBX V3.0.0.6 64,544 04-28-93 12:00a V1.0 GPF'd with: THREED.VBX V3.0.1.0 64,432 07-16-93 3:28p V1.05 contains: THREED.VBX V3.0.2.0 64,352 The file should always be located in the \WINDOWS\SYSTEM directory. Version 1.05 contains an updated THREED.VBX plus fixes that should eliminate this problem. FB10502 Version 1.0 contained a couple minor bugs that caused labels to become positioned incorrectly following resize of one of the figures attached to the connector. FB10503 Version 1.0 contained various minor bugs having to do with dialog control graying in the properties dialog box. FB10504 Added several performance enhancements. Redraw speed increased 10% for non-selected items, 20% for selected items, and 33% for drag outlines. FB10505 Fixed 13 class 5 bugs, rarely affect usage/no serious results FB11001 Version 1.05 contained a potentially serious bug that can occur when copying multiple figures with different fonts (but does not occur when copying all figures). The result can be a figure font that changes when it shouldn't or in some cases a crash. It is also possible for the error to be saved in a diagram file causing the program to crash each time the diagram is opened. Version 1.1 fixes all aspects of this problem. For users of versions 1.05 and earlier, if you have a diagram file that causes a crash every time you load it, use a text editor to edit all figure definitions to use font 0 (as shown below), the open the diagram, and reset all your figure fonts. Figure 24 { <other fields...> Font 0 <other fields...> } FB11002 Version 1.05 contained many visual anomalies when run under Windows 95 in conjunction with a non-standard color theme. FB11003 Version 1.05 contained an annoying bug that could cause unattached connectors to move small amounts relative to nearby figures whenever you move a group of figures, copy, paste, and so on. This effect happened whenever snap-to-grid was enabled and some of the figures moved had the snap-to-grid property AND unattached connectors were moved as well. The problem was that the figures would snap to the grid but the connectors would not. The fix enforces that whenever a group of objects is moved, they are all moved the same amount. If a particular figure is not aligned on a grid point, and you want to snap it to a grid point, you must move it alone. FB11004 Version 1.05 would not allow you to align two figures (the menu item was grayed unless three or more were selected.) This has been fixed. FB12001 In all previous versions copying or cutting selected characters could cause a General Protection Fault (crash) if the number of characters was evenly divisible by 32. This has been fixed in V1.2. FB12002 International characters are now valid (sych as German umlauts). Use ALT+0+Ansi code to enter from US keyboard (e.g. 'ae' is Alt+0230) FB13001 Exporting to a metafile now works properly when overwriting an existing file. Previously, it appended the new data to the previous file. The work-around is to delete the file then export again. FB20001 Text scaling and truncation problem. DESCRIPTION: Text does not scale as precisely as other objects in a diagram. This is primarily a limitation of the Windows operating system that we have not found a good method to get around. Text can only scale to even point sizes 4pt, 5pt, 6pt. However, diagrams can scale to any degree. The rounding that occurs usually picks a smaller text size if the exact size is not available, however occasionally, the larger size is chosen inadvertantly. SYMPTOMS: Ends of text labels can occasionally be cut of on print-outs. At certain zoom percentages, text seems to be cut off in a figure or label near the edges. When a figure expands to the size of its text, sometimes it will not seem to expand to the proper size. This has now been fixed and should very rarely if ever occur any longer. FB20002 When you scale objects, connector ends that are not connected to any objects do not always scale proportionately to other objects throwing off alignment. Fixed. FB20003 Select range of text and chaneg font size, intermittently causes a crash. Fixed. FB20004 If you select a figure, then start editing text size on the tool bar, then hit delete, the figure is deleted NOT the text size - similar if editing zoom. Fixed. FB20005 When you are in the middle of editing text and you type such that the text and cursor extend off of the screen, the screen should automatically scroll so that the cursor remains in view. Fixed. FB20006 When you are in the middle of editing text and you scroll using the scroll bars, text background is not updated properly. Fixed. FB20007 When you are in the middle of editing text and you click the show grid toolbar button, the text background doesn't adjust right away. Fixed. FB20008 Version 2.0 and previous versions contained a bug that prevented symbol fonts (for example WingDings) from displaying as symbols. This has been fixed. FB20009 FB20001 still applied to vertical text spacing under some zoom percentages. The bottom text of a figure would sometimes be cut off partially or completely out of site. This has been fixed. FB20010 Space Evenly will not always move all selected figures When you select a number of figures, then choose Space Evenly from the Figures menu, some or all of the selected figures will not move as expected. This has been fixed. FB20011 Align will fail to align some figures on occasion. When you select a number of figures, then choose Aign from the Figures menu, some or all of the selected figures will not move as expected. This has been fixed. FB20012 Loading a diagram saved by V1.2 wiht "Save all Fields" option enabled doesn't work - figures appear as outlined boxes. Fixed. FB20013 A very unusual and rare set of circumstances would cuse the program to hang when you drag a slected connector. Fixed. FB20014 If you enter text mode, click on an arbitrary location, then click at another place before entering text, an odd box will appear on the screen occasionally even a crash. Fixed. FB20015 Connector ends moving when they should not DESCRIPTION: An unattached connector should stay straight. If it is vertical, it should stay vertical when you move it with a group of objects. However, there is a bug that can cause certain connectors to slip from one end or another when moved. This will only occur if the connector is dragged above or to the left of the 0,0 mark on the ruler bar. This is a much less serious problem than FB11003 which has been fixed. FB20101 If you had a diagram open, create a new diagram, and try to save the new diagram to a file with the same name as the other open diagram (choosing yes when asked to confirm), you got an error message box that was blank. It now closes the old diagram. FB20102 Under some conditions, it may become impossible to enable the grid for a diagram. This is now fixed. FB20103 In text mode, scrolling repeatedly with the scroll bar can cause a crash. Fixed. FB20201 EDGE did not operate properly with certain printer drivers especially those that used non-standard paper sizes such as plotters that used D or E sized sheets. This is now fixed. This change required a change in the way that diagrams are saved. The complete printer set-up and page layout is now saved in the diagram in structures called 'DevMode' and 'DevNames'. Diagrams saved by previous versions will load with this version, but diagrams saved by this version will NOT load with previous versions. In a bind, you manually edit a diagram saved by V2.02 to be loadable by V2.0 or V2.01. To do so, load the diagram (.EDG file) into a text editor and delete the line that starts with the text 'DevMode' and the lines that follow from the '{' to the '}'. Do the same for 'DevNames'. Also change the version (2nd line from 2.02 to 2.0) FB20202 When you print across multiple pages (poster style), one letter on each line of text in a figure that crosses the page boundary is cut off. The printer itself is cuting out the character because it is trying to use its internal fonts or downloaded soft fonts. To solve this problem, go into printer set-up and chosoe the option that is called "Print fonts as graphics" (or "Print TrueType as graphics"). With this option set, the characters inquestion will be printed partially on one page and partially on the other. The bug in all of this was that this option was not being saved with the diagram - you had to go into set-up and choose this option each time your ran EDGE. This is now fixed. +------------------------+ | | | EDGE Diagrammer | | | | KNOWN BUGS (unfixed) | | | +------------------------+ KB10001 Multiple text areas highlighted simultaneously. DESCRIPTION: While editing text in a figure that has multiple text areas, pressing the tab key twice in rapid succession causes both text areas to be highlighted improperly. WORKAROUND: Don't type so quickly. KB10003 Endcap colors don't match connector colors when printing. DESCRIPTION: Endcaps are the squared-off areas that EDGE Diagrammer adds to connectors that are thicker than 3pts and are vertical or horizontal or meet another connector at a ninety degree angle. On the screen, the end cap color always matches the color of the connector. However, when printing, o after pasting to another program, the endcaps can become a slightly different shade than that of the connector. This occurs because the line color must be a solid color on the output device (either black or white on a black and white printer!) while the endcap uses dithering to achieve a closer match to the true color. WORKAROUND: Avoid fancy colored connectors if they are thick and you want to print them to black and white printers. Or avoid endcaps. You can prevent endcaps by keeping thick labels slightly off from vertical or horizontal by turning off snap an moving one end slightly. KB10004 Tooltip drop-outs over rulers. DESCRIPTION: Occasionally, a small piece of a toolbar "tip" (the little help balloons) is left drawn on top of the ruler bar. We have not been able to isolate exactly how this is caused. WORKAROUND: The problem is only visual. You can clean up your display by either toggling rulers off then back on, or resizing your main window to force the screen to repaint. No harm is caused by ignoring the problem. KB10005 Figure text edit overlapping other figures. DESCRIPTION: If you edit text for a figure that is "behind" other nearby figures but is not overlapping those figures so that it doesn't appear to be behind them, and then you add text such that the figure automatically expands to such extent that it now overlaps the other figures. In this unusual case, the other figures will appear between the figure and the text until you cause a repaint. KB10006 Connectors, text, and border don't draw in the color I want. DESCRIPTION: As explained several times in the User Guide and on-line help, connectors, text, and figure borders (anything drawn with lines), has to be drawn in a color that can be drawn solid on the output device. In the case of a black and white printer, the only solid colors are black and white. On a 16 color video display, there are 16 different solid colors. Windows can create other colors on the screen for fills by dithering (adding patterns of multiple colors) but it cannot do so for lines or text. Therefore, it you choose a dithered color like blue-green and try use that color as a connector color, the connector will actually be drawn in the nearest solid color (blue or green on the display, black on a black and white printer.) WORKAROUND: For text and lines, use only colors that can be drawn solid on the output device that it will be drawn on. If possible use a 256-color display mode, and if you want to get fancy with colors, consider a color printer. KB10007 Dashed or dotted connectors must be 1/4 pt. DESCRIPTION: When you try to create a dashed or dotted connector that is thicker than 1/4 pt, the point size reverts back to 1/4 pt. This is simply a restriction of styled lines. Only thin lines may be dashed or dotted. Our only practical alternative was to disallow dashed and dotted lines altogether. KB10008 Some point sizes are not allowed. DESCRIPTION: Although point sizes (for connector thicknesses, figure border thicknesses, and connector end sizes) are displayed as decimal numbers and are entered as decimal numbers, they are in fact rounded to the nearest 256th of an inch (or 100th of a cm.) for internal storage. Therefore, the numbers you enter get rounded to a number than can be used internally, then rounded back to decimal for display. For example, point measures can be made no finer than 0.25 points (0.25, 0.5, 0.75, 1.0, 1.25, and so on.) In fact, some whole numbers are best represented by a slightly different value. For example 10pts is not possible to display because 35/256ths is closer 9.75 than to 10.0 and 36/356ths is closer to 10.25 than to 10.0. Therefore, EDGE Diagrammer stores 10pts as 10.25pts, its closest match. KB10009 Can't paste some characters into figure or label text. DESCRIPTION: A few special punctuation characters cannot be added to figure or label text. The tilde "~", vertical bar "|", and accent grave '`' are reserved for internal usage. If you try to paste text from the clipboard that contains these characters, they will be stripped out of the text. -------------------------------------------------------------------------- Please report any bugs you discover, CompuServe E-mail (72162,1672) is the best method, or from the Internet 72162.1672@compuserve.com Thanks.
