I am an Electrical Engineer attempting to run a USB oscilloscope through the guest operating system, and hence the scope's accompanying driver and software. The software and driver work on a standard XP pro system, and they have installed flawlessly in the Guest OS. Unfortunately when the software opens on the guest the resulting image is scrambled (see below). I believe the drivers are correctly installed and the functionality of the software is still intact because I can use pieces of what we can see in the image to drive the scope.

I have tried increasing the video memory allocated to the Guest OS and various combinations of guest screen resolutions, including fullscreen and standard settings for the Guest OS and USB scope program. Changing the screen size of the program appears to change where the various menus and boxes overlap each other, but things are no less miss-aligned. While this is not a 3D application, could it be attempting to use graphical code not supported by VB? Thank you in advance for any suggestions you may have.
