6502	Some WPF apps switch the desktop to 640x480	Andrey Rahmatullin		"Some .NET applications (such as Help Library Manager from VS2010 and the HgSccPackage commit dialog) automatically switch the guest desktop to 640x480. The original resolution is restored when the window is closed (the commit dialog apparently isn't destroyed when closed, so Visual Studio should be closed to restore the resolution). This happens only on the first launch in a session. These applications use WPF, but I can't say anything more specific about them, and most other WPF apps don't cause such behavior.

The log contains several lines such as 
{{{
Display::handleDisplayResize(): uScreenId = 0, pvVRAM=b1659000 w=640 h=480 bpp=16 cbLine=0x500
}}}"	defect	closed	guest additions	VirtualBox 3.1.6	fixed			Windows	Linux
