Windows XP SP2
Office 2003 SP1

I have a workstation at a client with the following issue:

A user periodically takes a screenshot and then pastes it into Word. All appears to be ok until the user scrolls a bit down into the document, and then scrolls back up again when the pasted image becomes plain white. If you save/re-open the document all becomes OK again and if you print it, the image prints out ok. The image doesn't appear to be removed from the document, it is just rendered as being plain white.

I quickly googled to no avail. Anyone have any ideas?

Thanks in advance
