OK, here's a simple script that does what (I think) you want.

NB - I decided to let Malte do the hard work and used AnimationEngine to 
check whether the mouse was within each hexagon; since Malte very 
generously put AE into the public domain, I see no reason to struggle 
through the maths again :-)

The following script goes into the card script; you MUST also put a copy 
of the mouseStillDown handler into each hexagon's script. (Note there is 
no actual dependence on them being hexagons).

btw - you can eliminate the mouseDown, mouseUp and mouseRelease 
handlers, if you can accept the very short delay until mouseStillDown 
kicks in.
