Problem
Program window or dialog box doesn’t appear on screen
1
Cause
Another window or dialog box may be covering the window or dialog box you want to see.
1
Solution
Move, close, or minimize any window or dialog box that may be covering the window or
dialog box you want to see.
2
Cause
Windows 98/2000 or NT 4.0 – If you’re using multi-display mode, the program window or
dialog box may be in a display or on a monitor that’s unusable.
1
Solution
Make sure all the displays and monitors you want to use are usable. For more information,
see other troubleshooting items in this guide.
3
Cause
The software may be using a display you didn’t intend to use or the software may be
configured to use more displays than the actual number of monitors you have. (For example,
you may be in DualHead Multi-Display mode but you only have one monitor.)
