My PC is at 10% CPU usage without the VB GUI running. Once the GUI and then the guest is up, CPU usage is at 15%. A little over an hour later, it's at 70% with one core pegged at 100% most of the time. (BTW, I get a lot of stuck/repeating keystrokes when load is high.) Shutting down the guest does not improve matters. When I close the VB GUI, I get an "is not working" error from Windows (details below).
Anybody know what's wrong? Is this a VB bug or something screwy about my system or installation?
Here's the performance data followed by my configuration. I'm going back to 1.6.6 until the next rev. Thanks for any help. I still really like VirtualBox.
