Hi there, That's exactly what happened to mine yesterday, well mine dropped an inch then it fell all the way into the door when i tried operating the window button.
I guess it's remove the door card, remove the foam cover then take the whole mechanism out, see what the problem is and or replace the necessary parts, Yep i know..it's pi**ed me off as well!

lol and i already have my drivers window to tackle for the same thing! damn n blast the thing! Ford Focus anyone!?
