Thanks, I'll give it a try, though thus far I haven't really needed any extensions for GNOME. I try to keep my install as stock as possible so as to report here accurately. I'll see if I can mailing list the GNOME guys, didn't get very far on IRC.

Like I said, this is something that will have to be taken up with Gnome
