Office 2007 tmp files show up after saving an edited document

Hi All,

Strangest problem I've come across to date :)  User has the following:

Windows XP Pro SP3 all high priority updates applied
Office 2007 Pro all SP and updates applied.

Whenever he opens up an existing Word, Excel or PowerPoint 2007 file, edits it and then saves it, a tmp file (in the format of but different letters all the time -  AEMXEPD.tmp) gets created in the same location, almost the same size as the original file itself.  This happens when he saves as a 2007 doc or even as a 97-2003 doc.  I've verified that this is the case only with existing documents in both Word and PowerPoint.  Couldn't get it to do it in Excel, but he says it's happened and after seeing it for myself I don't doubt him.

Here's the strange part.  I did a clean reinstall of his laptop, OS and Office, applied all updates, gave back his machine and voila it started happening again after he started working on some existing documents that same day.  He says he hasn't installed anything or made any system changes to his machine, but sometimes tryng to figure that out can be half the battle as well ;)

My best guess is it may have something to do with an existing file he may have opened that for some strange reason (could be infected with something) made some changes to how Office saves existing files.

Any help would be appreciated.  Thanks!
Kenny
