Thanks GFX, you've hit the nail on the head there. Crashes do seem to occur when clicking on facebook pages mostly.

I know IE8 is still Beta, but was kinda hoping it would be more stable than 7, but the same problem occurs.

And to all the other replies, Thanks too, but as I said earlier in the thread at least one essential work site will only work through IE4 and above (but not 8?) or etscape so merely changing browser isn't an option.

Would love a Mac, but this is a company PC so I can't be picky :o(
