Kerry My Windows 7 (RTM) will just vanish. On window restart it complains that the machine was not shut down as expected. Has happened several times (per day) and I can't identify any particular user action that triggers it. Always seems to happen when I have lots of applications open. Task Manager (in Windows) shows around 1GB of memory allocated. I run Win7 full screen. defect closed other VirtualBox 3.0.6 fixed OSX Win7 Windows7 Windows Mac OS X
