Experience something strange, and it was repeatable. Like all windows programs CS has the 3 buttons in upper right hand of window. From left to right, minimize,full screen, and exit. When I open CS, it normally opens in a smaller window. If I click the full screen button, it goes to full screen. If I later reclick the full screen button, the window returns to normal size. Operates just as would be expected. BUT... if I click full screen and then exit, when I later return to the program, it opens full screen, and is stuck there. Clicking the full screen button does nothing. Can't ever get it back to regular window. Even after rebooting it stays stuck. The only way I got it back to normal was to use Go Back and revert the disk back to a point before, I did this. Tested and it is a repeatable condition. Running XP pro, with TDS,PG,WG3,ZAP 4.53, Spywareblaster,Spywareguard. Everything else on the machine seems normal.
