I'm running Windows 7 64 bit as the host and Ubuntu 11.04 32 bit as the guest on VirtualBox 4.0.12. Even in single monitor mode, if I use the Ubuntu guest VM to go to a website that uses flash video and run the video for a while, eventually, the entire system will lock up and I'll have to restart the VM. Anyone else have this issue? I can't figure out what is causing it.
*Additional note: I'm running the Gnome interface in traditional mode (so I can see the panels on the top and bottom of the gnome desktop).
