I seem to be a bit cursed of late. Somehow, I manage to press a sequence of keys that hides certain windows and locks up Photoshop 7.

What happens as a result is that the window that is open (if one is) is unresponsive. If I open the "Force Quit Applications" window, Photoshop appears normal. It also appears normal when I right-click it in my dock. I'm running Tiger on my Mac OS X so we have a dock that contains some applications.

This is the 5th time it's happening to me and I haven't a clue as to why. Any help would be greatly appreciated.

What the heck am I doing? What am I pressing? I thought I had hidden it so I pressed Command-H (Ctrl-H for PC users) but nada. I'm only running two other programs and was only working in PS when it occured.
