I haven't tried uninstalling / reinstalling, i really should have done that first. Will try later.
It's not IE8 causing the BSOD though. In this case it's the ATI graphics driver causing it. I can also 'induce' BSOD's by faffing with a USB bluetooth dongle - that has exactly the same affect on IE passwords.
Part of the problem is that IE8 also loses all it's passwords when I have to forcibly reboot the PC after it hangs (no particular reason for the PC hanging....just random and infrequent Microsoft issues!).
The password issue is not serious, it's just annoying me that I don't know what's causing it to happen.
