WorldClock fits the typical description of a Desk Accessory - a program that resides in the ∩ú┐ menu, waiting to be popped onto the screen to obtain some quick information, then put away again. As a Desk Accessory, WorldClock has no designated memory area of its own in which to operate, as does an Application Program. This can cause problems when the amount of available memory is marginal.
WorldClock operates in an area of memory, called the System Heap, that is shared by the operating system, extensions, window structures, and a variety of other goodies. The system heap is a very dynamic place, with things being moved around all the time. WorldClock has been extensively tested on a wide variety of Macs with varying amounts of installed memory, running a variety of different programs, and seldom has there been any trouble. If there isn't enough memory to run WorldClock, the program should advise you of this fact with a dialog box. If this happens, try putting away some windows, or quitting an application program to free up more memory and try again.
WorldClock Lite, a shareware version that may be downloaded from a variety of systems such as America Online, CompuServe, or a number of archives on the Internet, is the best indicator that WorldClock will operate properly in your Macintosh if you order it. If WorldClock Lite runs OK, then WorldClock should run OK, too.
Recommended Configuration: Macintosh II or Macintosh LC or Macintosh SE/30 or later. 68020, 68030, 68040, or PowerPC processor. 4.0 MB RAM or more. Floating Point Unit desired for additional speed, but not required.System 7.0.1 or later. Color or Grayscale Monitor Preferred (Monochrome Acceptable). WorldClock will not operate on earlier 68000 systems, such as the Mac 512, Classic, Plus, original Macintosh Portable, or PowerBook 100.
Recommended Control Panel Settings:
Monitors control panel:
Color Monitor: Thousands of Colors or Millions of Colors for optimum display of twilight depth
at the terminator between day and night. If your monitor does not support one of these color
depths, then 256 colors is the next best setting. Grayscale monitors are optimized for 16 grays.
Date and Time control panel:
Date: U.S. Format Time: U.S. Format
Some features of WorldClock will not appear as intended if other formats are used.
Map control panel:
It is not recommended for you to change settings via the "Map" control panel if you are using
WorldClock. WorldClock sets the system location to the "Home Location" you have selected,
when you select the "Save" option upon closing the program. In this regard, WorldClock
performs the same function as the "Map" control panel. If you are using WorldClock, there is
no need to use the "Map" control panel. In fact, changing the settings using the "Map" control
panel may confuse WorldClock and result in incorrect displays.
Windowshade control panel
WorldClock does not work correctly with Windowshade. Problems may occur if you "roll up"
the WorldClock window using Windowshade, and then choose another option from the
WorldClock menu while WorldClock is hidden. If you are using Windowshade and do roll up
the WorldClock window, DO NOT choose another item from the WorldClock menu while the
window is still rolled up. There is no problem if you roll the WorldClock window back down
and then choose another item from the menu.
Using Multiple Monitors
If you are using a second monitor with the same number of colors or grays as the main monitor,
WorldClock will display correctly if you drag its window to the second monitor. If the second
monitor is set for a different number of colors or grays than the main monitor, and you want
WorldClock to be on the second monitor, drag the WorldClock window to the second monitor
and then close it from there. When you re-open WorldClock, it should come up on the second
monitor, adjusted for optimum display there.
PowerBook Display
Some PowerBooks have a 640 x 400 pixel display instead of 640 x 480. On these PowerBooks,
WorldClock adjusts its large display option to fit by truncating the north and south polar regions.
