I've got a strange mis-alignment issues with passenger and driver side power windows.

I lower either window down partial (doesn't matter is it's half way or and inch) from closed position and windows slides down effortlessly that first time.

When I push the button again to lower the window down further it makes a "click" sound.
The click is the sound of the window hitting on the frame as it gets pulled down by the motor.
(My 06 didn't have this problem because it didn't have a frame.)

Anyone else with this problem? Any easy possible fix other than take it to the dealer?
Did the window get shifted off it's mount over time?

Thanks for the help all
