I am running VirtualBox 3.12 on a Debian Squeeze install running the Debian Lenny version of the VirtualBox .deb file install. Upon upgrading from 3.10 to 3.12, after logging into Windows XP an instance of explorer opens the My Computer window. When this window is closed it opens right back up. When it is minimized, it restores itself. When I double click on an item in it like C:, it goes to that location and then another window for My Computer will open up. The window also constantly attempts to gain focus so even using your Start menu is impossible. The window even goes on top of Task Manager when task manager is setup to always be on top. This problem was fixed by downgrading to VirtualBox 3.10 again. The upgrading of VirtualBox Guest Tools in the Windows XP guest made no difference what version they were at (3.10 or 3.12). I also had the experimental Direct3D support installed with the Tools and enabled. Additionally the Windows XP SP3 guest is running the ""Advanced Configuration and Power Interface (ACPI) PC"" Windows kernel under Device Manager->Computer. This also occurred no matter what user I logged into Windows as. Rebooting the guest or the host did not help." defect closed other VirtualBox 3.0.12 obsolete Windows Linux
