I have been using AI 9.1 for quite a while now with absolutely no problems. Suddenly, the entire program has slowed down. Especially when I try to drag pallets around or draw shapes. The only thing I can think of that I have done recently is that I uninstalled an AI 10 demo that I had downloaded from the Adobe site. I have uninstalled and reinstalled all versions of AI that I have (7.0 through 9.1) with no improvement. Can anyone offer any suggestions?
