The entire computer crashes, meaning that you have to restart it from scratch? Or is it just that the browser or viewer crash (i.e. Quicktime)?
the entire system crashes, only way out is a hard reset (holding the power button down)
Is it quicktime?
I think it's some sort of media viewer built into the browser
same thing happens on both firefox and safari
It's generally a bad thing for the machine to be hard powered off in the manner you describe - in fact, doing so can exacerbate the problem.
I'm only doing what I'm told, WHY DON'T YOU UNDERSTAND THAT?
After that, you're on your own here, my friend. Completely inappropriate.
