My controls in Photoshop CS3 have started going wonky.

Question

Some require a double-click now, some hotkeys have to be hit twice, and others simply do not work. Worst of all, this also applies to menu selection - expand selection, for example, simply does not work at all.
I have not installed anything new recently, but may have hit the wrong thing on the keyboard by accident (a cat decided to tap dance her way from one side of the desk to the other).
Help? Adobe seems to have abandoned any way to contact them by phone.

Answer 1

First you need to at least update photoshop cs3 to 10.0.1 and any other cs3 updates you might need from here:
Adobe - Creative Suite : For Windows
Then i would reset the photoshop cs3 preferences.
reset preferences
Press and hold down the Shift+Ctrl+Alt keys just after starting the launch of photoshop cs3
Keep holding the keys down until you get a dialog asking if you want to delete the adobe photoshop settings file
Press Yes
