Dear all,

I have a problen concerning what I see on the excel screen.
While working in Excel (normal things as comparing, copy-paste etc.)
parts from the screen become blank, to come back seconds later (some
times 4 other 10 or longer).
When this occurs I mostly switch to another application and go back to
excel (2x alt-tab)
I had this problem on my previous laptop and still have it on this new
one with a complete fresh install.

You can see some print screeens on the links below.

Can anyone help me or give some indications what the issue may be
here?

I have:
Newest HP probook
MS Windows XP professional (up to date)
MS Office 2007 (up to date)
HP monitor
Latest update video drivers from HP site
Latest update monitor drivers (HP site)

Best regards,

Ronald.
