Has anyone seen anythink like what is happening in the Excel
screenshot below ..

http://www.jon-lamb.co.uk/tf_excel.gif

The text is corrupting in cells. Its just happening on one PC and in
most excel documents on that PC. It seems to happen a lot when cutting
and pasting. So far, I've installed all office and windows updates,
removed the anti virus software to test. Installed all graphics
driver updates.

PC spec is XP Pro, Celeron 3.2GHz, 2GB RAM. Office 2003

Any help much appreciated.

Rgrds,
Jon
