"cleaning up" drag and drop

puzzled…

http://neumenex.com/e-archives/drag_test.fla

i am confused about a few things. i would like to be able to make the buttons become invisible (i have that) after being dropped and also, return to their starting location (this is what i need help with). also, i notice that unless you drop the button in a specific location, the target will not update. is there a way for me to make a larger area? when you test my movie you’ll see that it takes about 90000 times to drop it in the “right spot”. thanks for the help!

can someone please help me?

i already figured out how to make it return to its original place. but i cannot figure out how to correct the “right spot” problem.

Where are your actions at? I cant find them…

this fla is before i figured out the placements…
anywho, the actions are located on the buttons inside the mcs
(they are along the left side)

is anyone else willing to help?
