Ok, when I got the iMac last year I had no issues with Flash player. I installed Leopard and my browsers started crashing whenever I tried to watch a video on Youtube, etc. So, today I did a clean install of Tiger, started fresh. Got rid of everything on my hard drive. Guess what....it STILL crashes. If I uninstall Flash they work fine. But, that defeats the purpose since I can't watch videos, etc. I reinstalled Leopard, same problem. It also crashes when I try to log into Amazon, and some of my credit card sites with flash content. Now, not all sites with flash content crash. I did a hardware test and it came back good. So....I'm stuck! HELP!!!
