Little edge selection bug after an undo.

 From:  PaQ
Hi Michael,

I just catch a little bug here:

1) Create a volume
2) select 1 or more edges
3) click outside the volume (so you deselect your edge selection)
4) Undo (the selection is back, that's great)

The problem is that you can't select any other edges until you move the camera.

Is it clear ?
