CloseView does have some known issues. Avoiding the following situations or using a workaround will improve your experience with CloseView.
- There are severe anomalies in multiple monitor situations when the menu bar is moved with CloseView active. This includes PowerBooks with external monitors. PowerBook mirroring to an external monitor should also be avoided.
- The System can hang in low memory situations with CloseView. CloseView performs its function in off-screen memory before displaying the results. In low memory situations, CloseView may cause a system hang. Situations which can lead to this are: 1) using big RAM disks 2) sharing built-in memory with PC compatibility cards. These situations reduce available RAM for CloseView to use.
- CloseView does not work properly with QuickDraw GX at all. This is because CloseView has patched all of QuickDraw and is unaware of QuickDraw GX.
- System occasionally hangs during restart when zoom set to 16x. Turn CloseView off before restart.
- System may hang if MacsBug is entered when CloseView is active. Turn CloseView off before entering MacsBug intentionally.
- Some anomalies have been observed when switching multi-scan monitor resolution modes with CloseView active. Turn CloseView off during monitor resolution switching.
- CloseView sometimes doesn't like monitors in thousands of colors. Use 256 colors when possible.
- The Finder crashes when clicking during a remote volume mount when PowerShare is active. This shouldn't be a problem with Mac OS 7.6, since PowerShare is unsupported under Mac OS 7.6.
Note: CloseView is written as a single word, not as Close View.
