Display options erratic in machine settings

[ebonweaver]

I have 3 Windows 7 machines created, and each one of them behaves entirely different in the Display section. While all 3 machines have the 3D option disabled, two of them have it enabled whiles being disabled. In other words, the box is checked and can not be unchecked, while the third is unchecked and can not be checked. Two of them state that 36mb is required for 2D acceleration, the third does not. The "third" in each of these cases is a different machine, creating 3 entirely difference behavior sets for no apparent reason. All other settings are identical. All machines work the same when booted, but these settings are all different and can not be made the same, so it's not clear what is broken or what settings they are actually using when powered on.
