This is a minor bug - if it is a bug at all. But it has a knock-on effect.
The next time you start to invoke a gesture, a line will appear from the last place you had the mouse down (in the last gesture) - to the first place you click in the new gesture.
here's some crap pics to illustrate:
point a shows start point when the mousedown event happens) - point b shows the endpoint - where the mouse is released.
1st gesture (e.g. grenade)
The option button is released before the mouse button. (no feedback about gesture success/failure.)
Then doing the same gesture again (green line shows line automatically drawn:)
Even though the mouse goes down at point a a line is instantly drawn b->a before the normal a->b line.
Does that make sense?
