Comment 11 for bug 270814

Since everyone who had this problem has been fixed, I'm marking this as fixed.
Sorry about the physics engine, Natan - I thought it would be better to fix a high-importance issue properly, and worry about the physics engine later. You'll just have to find out where to put the bits of code for starting and finishing 'moves', and possibly correct the setting of 'self.dragged' and 'self.mouse_down'.
