I had the same problem with Ubuntu 7.10 running in VMWare. I was not
able to fix it. My solution was a system-upgrade to 8.04. The problem
disappeared. I just hope it does not appear again. Some other users
discovered the same problem and were able to solve it with an upgrade, too.

Sorry not to help you,
Jens
