Photos No Longer View in Full Screen

[Jasper7267]

My photos will no longer show in full screen in Windows Picture viewer or my screen saver. I recently installed the latest Illustrator CS4 trial. That is the only thing I have done to my brand new computer.

The program orientation may have changed. Right click on a particular picture file, go to the properties menu (at the end), and see the "open with" option there. If it opens with Illustraror, change it to windows picture viewer.
