I don't know what to think -- I opened MSIE and made it the default, and a link in an email in Outlook opened a window in MSIE just fine.

I then went back to Firefox and made it the default browser. I tried an email link, and it's the same problem again -- no new window opened in Firefox, and I got the same error message.

I'm still Googling the problem, but appreciate any and all suggestions.

cheers,
