[nfbcs] Trouble with IE8

[Tracy Carcione]

For the last 2 days, I've been having problems with IE.  It happens with any 
site; one time it hangs, and the next time it's fine, probably. It seems 
random, but it's happened several times.
I get the "program not responding, end now?" message, followed by the IE 
error report screen.  Before it abends, it hangs up for a while, and I hear 
the computer fan running like mad, but Jaws won't say anything.
I've run a virus scan with MS Security Essentials, and it didn't find 
anything.
I'm running Jaws 14 and IE8 on Windows XP Pro.
Is there any way to find out what's happening when IE hangs?
If I reinstall IE8, will it cause a disaster?
Does IE9 work?  I remember hearing there were problems with it.
TIA.
