In the attached screenshot you can see the Windows desktop (blue) and the Ubuntu desktop (black) with an instance of Firefox running in Ubuntu and the VirtualBox console running in Windows. Notice that the Firefox window overlaps into the Windows desktop but the window border is missing on the portion that overlaps the Windows desktop. The Ubuntu desktop is truncated to about the top third of the screen but windows contained on it are still visible below that. ''Notes:''[[BR]] 1. Seamless mode with a Win2K3 guest works properly which seems to indicate that the issue may be related to the Linux x32 Guest Additions. The guest OS is a factor. 2. Tested with the host display resolution at a lower setting and seamless mode with the Ubuntu guest works properly. The host display resolution is a factor. 3. Tested with a second monitor connected and without - results are the same. The second monitor is not a factor. 4. Tested with the Windows Taskbar at the top and bottom of the screen - results are the same. The location of the Windows Taskbar is not a factor.
