Bueller? Bueller?
I'd still like some more info on this from you guys, if you get a chance.
This area is a little tricky in that we are trying to be careful to not arbitrarily steal focus from the application you're using just because you opened a new guest application. So we do have a couple of bugs open internally that are about this problem and I'll be looking into those soon.
Sorry you're hitting problems like this. Thanks for the problem report though. Please keep 'em coming! =:)
