Instead of disengaging the object why not set a constraint to the hand? Initialising physics objects is slow too so this may also provide a performance boost and make things simpler.
Ok knuckleheads, listen up:
Their = Belonging to, ie "Their wives had beards".
There = As in "Look over there"
They're = Short for "They are"
L O F I G A M E S . C O M
