Beacuse the video card is a "mobile" crad, NVidia is likely to tell you that updated drivers are only available from the laptop maker - Dell in this case. (that's the way ATI deals with drivers for their mobile cards).
Before mucking with video drivers which are pretty touch and GO with the GO cards at the moment, check the settings of the door object. It may be simply a matter of adjusting parameters for this door and all similar doors.
In the part browser, set the library preview mode to shaded view and hit the "Model" tab. Make sure that the "Use Object's Materials" checkbox is checked. To test, Unchecking it will change the appearance of the glazed part of the door in the preview window.
Fiddle with this setting and it should correct the problem.
Hope this helps.
