Also, If you move mouse from A to C, it should appear in bottom left corner of B.
But maybe it would be nice, if it will appear at proportionaly same height at second screen. For example, A is 800px height, B is 300px height. If mouse is 400px from top of A whem moved from A to B or C, it should apear 300px from top of B (50% -> 50%). Same idea should work when moving up and down.
It could behave wierd while draging something, so if any button is down, this nicer behaviour should be disabled (?).
