I bought my first iMac the other day. I'm incredibly happy with the purchase. The only issue I've had is how often programs crash. I expect my Office programs to crash (it's a weird copy of the software that I got from a friend) but my internet browsers - Safari and Firefox both - crash constantly. I don't know what prompts this. It seems very random. I'll be running everything pretty normally one minute and then have a crash the next. I've been using Leopard on a MacBook for about a year and have probably seen one crash total before this. Any thoughts?
