me too.. althought it doesn't open infinite tabs - what it does is OPEN INFINITE NUMBER OF WINDOWS UNDER INTERNET EXPLORER! Keeps going - if I go to Task Manager and kill the main program "Iexplore.exe" it stops and deletes all the subsidiary windows and everything seems to be fine - no damage or anything - just annoying. Options->program under tools says to use Windows Live for sending email links - that's my main mail server and it is perfectly fine.

You get tabs opening endlessly if you select the Firefox program to handle a file when you get an "Open with" dialog. You should never do that because Firefox wouldn't ask if it could handle this.
