Hey guys,
Sorry that this bug is so... buggy. 0_o Yeah, this is a frustrating one.
I don't have a better solution right now than to use an older release if the older release doesn't have this bug. That's the bad news.
However, I can definitely tell you that I fixed a bunch of really buggy behavior around popup menus and focus problems internally and these bug fixes should be Coming To A Future Release, Near You! Obviously, I can't tell you exactly when that will happen, but I wanted you guys to know that I appreciate you reporting this obnoxious bug and that we're paying attention. So please hang in there and keep the bug reports coming! =:)
