Video not refreshing 2008 SP3.1

Hello,

We have an excel sheet that we embed in to some drawings.

The problem occurs when I double click on the table so that it canbe edited. Once the edits are done and I return it to the drawingmost of the toolbars on the left hand side do not display properly.

Pushing SW down to the task bar and bringing it back fixes theproblem because the screen has to refresh.

We have Dell Precision 490 workstations, with NVideo QuadroFX 3450XP Pro sp2. I have updated the video drivers to the latest SWcertified.
