Comment 6 for bug 571944

It just happened again, and this time I was doing an Alt-Enter auto-import hints thing in the editor. I noticed my pointer was in the editor but NOT in either of the pop-ups that came up, so disregard that idea. This reminds me, though, that I have seen this problem happen with the mouse in the editor pane and in the Projects pane. Wherever the mouse is, that is where the selection seems to be anchored (selecting source in the editor or selecting files/folders in the Projects pane).
