9636,Windows XP command prompt crash with guest additions -> Fixed in SVN.,bob3248,,"Host: Windows 7 SP1 64bit VirtualBox 4.1.2
Guest: Windows XP Pro SP3 32bit, clean install, default VirtualBox options except 512MB RAM, using VT-x acceleration

If I open a command prompt, it opens in a window and works normally. I can press Alt-Enter to change the command prompt window to full screen and that also works normally. However, if I press Alt-Enter again to return the command prompt to a window the virtual machine hangs with a black screen. It then either remains frozen so I need to power off the virtual machine or reboots after a few seconds.

This problem only happens if the guest additions are installed.

The same issue is present under Windows NT 4.0, Windows 2000, Windows Server 2003 R2 32bit, and Windows 7 32bit.
64bit Windows systems are not affected because they cannot display a full screen command prompt.",defect,closed,guest additions,VirtualBox 4.1.2,fixed,command prompt,,Windows,Windows
