It could also be due to the fact that you have to many fonts installed. I had over 5,000 fonts installed which caused my CS2 to lag and stop working from time to time. I would be jsut about done with a project and then die on me.
I just reset my fonts back to the original fonts installed with XP and only installed the necessary fonts to finish my work. It solved my issue.
