Ubuntu in Virtual Box slows way down . . .
I'm running Ubuntu in a virtualbox on a Windows 7 host. It works great - except after I start up the machine, the response to keystrokes and updating of the screen slows way down. It gets slower and slower until it is unbearable after about an hour. If I save the machine state and reload it, things work great again - so it sounds like a virtualbox problem, not an ubuntu problem.
Do other people who run Ubuntu in a virtualbox see this behavior? Do other people who run virtualbox in Windows 7 see this? Does anyone know how to fix this?
