Working with XP Pro - latest IE7

I cannot opened up any new pop up links (e.g www.theglobeandmail.com click
any media files) in new windows or tabs (my tabs settings). But the link can
be opened in the original tab.

I have run through Opening IE without Add-on, Reset IE settings, changed a
bunch of tab settings, disabled all add-ons, enabled/disabled pop up blockers
- still no luck.

My Symmatec and Windows Defenders said my computer is running healthy.

Unfortunately, IE is the default browser for my company. I cannot switch to
Firefox.

I am getting very frustrated. I am stop short of uninstalling IE 7. But you
know sometimes the Microsoft uninstalling might not work. Any help???
