On Mac OS X, dragging a JGoObject will produce a copy action rather
than a move. The mouse modifiers imply a key is being pressed
when there is none being pressed. Holding down ctrl while
dragging gives the desired behavior.
This is how the demo apps work out of the box and I’ve attempted to fix
the issue in my own code without any luck. Is JGo simply not
supported on the Mac, or is there some way I can get it working?
