Hi folks,
I face this bug with VirtualBox 2.x and 3.x, running a WinXP Pro Guest under both - WinXP x64 and Ubuntu AMD64.
Certain applications like Internet Explorer and FritzBox USB-over-LAN put VirtualBox into some endless resolution switching loop - it permanently switches the screen resolution, i.e. screen flickering and window resizing and it is very hard to get control over the virtual machine.
It doesn't seem to matter, if I have Direct2D/3D support activated or not.
Guest Tools are up to date.
Has anyone else faced this? Any known solution?
Cheers, Andi
