Found fix for this at Mozilla: http://kb.mozillazine.org/Default_browser
Apparently, even though it LOOKS and ACTS like Firefox is still your default browser after an IE7 upgrade, it's not. To fix, you must run: firefox.exe -silent -nosplash -setDefaultBrowser Which also fixes the webbrowser. py problem. At least so far. rd -- http://mail.python.org/mailman/listinfo/python-list
