Dragging from top bar stops working

[abeisgreat]

Binary package hint: unity

I've been using unity since the official release of natty and at first the ability to maximize windows and have the controls pushed into the top bar worked fine and it still works fine. The issue is that attempting to unmaximize the window by clicking and dragging on the top bar has stopped working. Now, when attempting to drag from the top bar, nothing happens and the window remains full sized.

I did some fiddling attempting to get dual monitors working, although only with X, nothing with unity specifically. I'm running the proprietary nvidia drivers, so it may have something to do with that.
