I'm still getting it. The symptom is the same as PremEx's: it works fine if you tell it which forum to search, but not if you search all forums (fora?). As distinct from Baze, it didn't matter if I searched for a single word or multiple words.

It's really sending nothing back. I checked the HTML source of the reply. It was empty. It's not like it's returning something that browsers display as a blank page.

Good luck tracking this one down!
