Screen redrawing problem in SolidWorks2008 with opengl

[denisb]

With NVidia 6800 : When SolidWorks 2008 runs in a XP box with 3D OpenGL activated, the screen is not correctly redrawn when the mouse is over any other part of the application except the graphics windows itself. The background image of SW window is then displayed. Only a small rectangle under the cursor is refreshed, but rotating the part or zooming refreshes correctly the window.

Sporadic application freezes when movingg or redimensionning windows

With Intel i865 : Solidworks graphics windows are not refreshed, and the application freezes.

Freely downloadable SolidWorks viewer has the same behavior
