After installation of the guest additions, I changed in the control panel of Vista the screen resolution to 1920x1200. Vista seems to support this new screen resolution. However, when I reboot the system, the screen is damaged completely. I can only see stripes with the color of the screen background. At startup of Vista I pressed the F8 key and selected start up with low resolution 640x480. Now, the screen is okay. When I set up the screen resolution in the control panel to 1920x1200, the screen shows the new resolution correctly. But after reboot of the system, the video driver seems to crash again with this high resolution. " defect closed guest additions VirtualBox 2.1.2 obsolete Windows Mac OS X
