We have about 1000 users at our organization, and about 50 or so are experiencing issues with toolbars in Word randomly changing color when hovering the mouse pointer over an icon, and the toolbar settings (positions) randomly changing. These changes are as though the user has moved a toolbar, but in reality, they have done nothing of the sort. The changes happen very infrequently (some happen a few days after resetting their positions, others take up to 3 weeks), and Word is used every day by each user. Functionality of the toolbars does not change; clicking Print still prints, etc. We are running Office 2003 Professional w/SP2 and the latest updates as of this posting. Some users have Adobe Acrobat 6.0 Professional, some users have 7.0 Standard. Some users have no Adobe other than Reader (which, to my knowledge, does not insert toolbars into Word). Some users have Hummingbird DM, others (most) don't. The machines are all Dell PC's, and range from Optiplex GX270's, GX280, GX620's. All Windows XP Professional w/SP2 and the latest updates as of this posting. All machines are actively scanned with McAfee VirusScan Enterprise on a daily basis, and have been scanned for malicious software - 99% of our users have "basic" user accounts, with very restricted access. Can anyone offer any insight as to why the toolbars might move around at random? We have re-installed Office on several machines, but the problem does eventually return. We have re-imaged several of the machines too, but the problem does return. We have tried restricting Normal.dot to read-only access, deleting Normal.dot and have it re-created. We are currently testing Modify access to HKCU\Software\Microsoft\Office\11.0\Word, which is showing promise... Thanks for any help anyone can provide.
