Documents Corrupt Display

[topdown]

Running Windows 7 and MS Office Ultimate 2007, with MS Word, Excel and Outlook I can be working on a document and when scrolling the display is corrupt. In excel the rows will appear to be duplicated and will overwrite the Menu bar. Same in word and oulook the text will duplicate and lines in the wrong order. To fix I minimise the dispaly and all is OK for a few minutes when it happens again.



If I save the document with the corrupt display it is ok when I re-open the file.

PC is a 2010 hp Pavillion dv6 but used to be the same on my Dell.

I did a search on display but could not find anything.

Appreciate any solution.
