It happened so fast, that I never even got to post the problem, but
maybe someone could use the solution.

DP G5 2 Gz OS 10.3.2 PS working fine, then all of a sudden, PS would
freeze repeatedly when opening Image>Image Size...

I muddled around for a while, and could not find the cause. Every image,
including a small new image resulted in PS crashing. I had to Force Quit.

The solution: I deleted the PS pref file from my Library, and it
corrected the problem.

Maybe this is general knowledge to everyone, but I wonder how often the
prefs just get corrupted like that. And how?
