Excel 2007 Switching between open files

[robindefoe]

I've recently installed a couple of new machines that came with Office 2007.

One user has come up with a rather odd problem in Excel. She is used to switching between open documents by using the keyboard (Alt+Tab) method, but with a particular worksheet she has found that the screen image becomes corrupted when she switches. If she merely clicks on the open files on the task bar she experiences no problems at all.

Has anybody else seen this problem yet? And are there any obvious solutions?

Thanks

I would check the graphics driver. Change acceleration or update the driver
