It seems as though these settings are probably configured in the Windows Registry.

You can try uninstalling Office 2007, go the Registry Editor (just go to Start -> Run and type "regedit" and enter). Make sure you are logged in with the problematic user.

In there go to  HKEY_CURRENT_USER\Software\Microsoft\Office

Stand on the "Office" element and delete it.

NOTE THAT PLAYING WITH THE REGISTRY MAY CAUSE DAMANGE TO YOUR OPERATING SYSTEM THAT MAY LEAD YOU TO REINSTALLING IT!

Do it carefully or ask someone that knows how to do it to do it for you.

After you do that, restart your computer and reinstall Office 2007. This should make things better since you have just deleted all of your Office 2007 configuration settings for your specific user.
