in the following cap
dragging an A or B box over a 1 or 2 will highlight it as picked
after that if you drag a picked 1 or 2 above the red line it should highlight the A or B box
click here for cap
if you go into the event sheet, and switch around which event is toggled
it behaves differently
there is only one difference between the two events:
the original event uses sprite-compare y position
and the second event uses system-compare sprite.y
should I post this to the bug tracker?
I was trying to recreate the bug from a larger cap where it had more serious effects
it also began with
for every A, pick B
and then after the system-compare, it would pick some unpaired objects that belonged to another pair
