MoorleyMan, you can install another browser on your computer but don't start it up unless you need it, in which case you would start that one instead of the other one to get to the internet. I do a lot of downloads from download.cnet.com (can't remember the exact name, and I'm on Safari which doesn't let me open another window, at least as far as I can tell right now - one of the things I miss about IE). Go there and search for Safari or other browser and download it to your machine.

I think the problem is IE, because I run Yahoo with Safari and don't have a problem, but IE and Yahoo crash. So apparently it happens with both IE7 and IE8. Or maybe it's a virus infecting IE.
