This question is urgent -- affecting my ability to do work.
Outlook 2003 will not open any hyperlinks within a message -- it just brings up "locate link browser" window, that is, a local file location dialog box. I noticed this behavior after I downloaded a user-agent extension for Firefox 1.0 -- something that completely screwed up my Firefox installation as well. It may be a coincidence, but it may have something to do with the Firefox entension. I have since removed the Firefox installation, docs, & user settings.
