Problem Program window or dialog box doesn’t appear on screen

Solution
Move, close, or minimize any window or dialog box that may be covering the window or
dialog box you want to see.

or configured.)

Make sure all the displays and monitors you want to use are usable. For more information,
see the other troubleshooting items in this guide.

configured to use more displays than the actual number of monitors you have.
