My GT had the problem on only the drivers door. Window dropped when door opened (10mm) but only returned half way (5mm) when door closed. Tried the 10sec reset a number of times but it made no difference. Ended up removing the door card and greasing the cables with silicone grease. Once the door card is removed you need to make slits in the vapour barrier to get your hand in behind the runners(about 100mm in from the front and rear of the door are the runners you will see a bolt top and bottom of each one), feel about and you will find the runners and at the back a steel cable. This is the cable I greased. make sure to close the slits in the barrier with some duct tape when you have finished. Fully opened and closed the window a couple of times, then reset with the button hold procedure. This cured the problem, also the window is much smoother when in operation.
