Odd error this. Am getting an Ubuntu crash once or twice each day when I close a Firefox tab ... happens if I'm a bit careless when clicking on the X of the tab ... if I'm really precise there's no problem.

Firefox 3.0.7, Hardy Heron.

Ubuntu just crashes to black screen, have to re-boot, then it all works fine again until the next time.

Tried searching for similar problems but they seem to be last year or 2007.

Not a major concern, just a pesky annoyance. Any ideas ?

Thanks in advance for any suggestions.

Niall.
