We are experiencing some intermittent display issues whenusing SolidWorks with several identical specification systems.

System configuration:
Intel S5000XVN Motherboard; Intel Xeon Quad Core X5460 CPU; 4Gb ECCDDR2 RAM; SAS HDD; Nvidia FX3700 Display Adaptor (Hewlett Packardcard); Windows XP Pro (32-bit); Solid Works 2008 SP5.0.

The following problems happen randomly when using Solid Works butare hard to reproduce on demand.

* SolidWorks toolbar icons turn black
* SolidWorks background turns black (ie. what is displayed when nodrawings are open) and Solid Works logo is not displayed
* Acrobat documents appear behind Solid Works window, but Acrobatwindow borders appear in front
* When rotating objects in Solid Works it sometimes fails torepaint them but partial object appears below mouse pointer whenmoved

When some of the above problems occur if you move the mous eoverthe effected area it may repaint it correctly, orminimize/maximize, etc.

We have tried many drivers, and are presently running the currentcertified drivers from the SolidWorks website.SolidworksAdministration
