i'm sure this must have happened to everyone a couple of times:

you cut a section of a patch, and paste it into another patch or subpatch.  the pasted contents overlay existing parts of the patch, and you go to move them with your mouse while they are still highlighted. 

however, sometimes your mouse just doesn't hit a part of the highlighted pasted objects, and the highlight comes off, and you're left with a big tangled mess of objects and patch chords.

other than just 'being super careful', is there any way to avoid or fix this problem without moving each individual object by hand???
