Exception in OnPaint3D on Windows 7, version 10.303.0.431


We've got an application that recently moved to windows 7, and for a small percentage of our users in a situation that unfortunately we haven't reproduced yet, we see the following exception.  Is this something anyone has seen previously by any chance?  A bit of a shot in the dark, but I thought I would post here as we haven't been able to get very far in diagnosing it.


(System.NullReferenceException) - Object reference not set to an instance of an object.
