and it's getting VERY annoying!!!! I'm working on this 1 hour project - hundreds of clips and stills. Sometimes all I have to do it slide the timebar, and the program crashes. Here's the error message. Does any of this technical mumbo jumbo mean anything to anyone?

I have 512 megs of memory, and a P2.6 computer. 2 huge hard drives.
