Might also want to disable IPv6 protocol within your network devices ;-)

cheers ...

I have unchecked the IPv6 box in Wireless Connection Properties, and when I go and check Wireless Connection Details it is no longer listed, altho in Status it is still marked as Limited, so I don't know whether it is disabled or not. Anyhow, it did not stop an IE8 crash a little later on.

qhn only - Have located in Event Viewer, the fault module for these crashes, which is ntdll.dll, and as that, according to Microsoft, can affect a hell of a lot of things, do not see any solution for that, anyway I am still getting these windows opening saying ie has stopped working, not that it bothers the operation of the comp in any way. I have noticed that it occurs mainly when I close a website or an application.
