I've had some window issues also, and my sunroof does the same thing every once in a while. Cold months, my windows roll down about 1/8inch too short and rub on the frame. A reset fixes it for about a week.
Could your issues be related to the pressure sensor? Although they're still prob rolling up too high, but maybe there's a way to reset the pressure sensor? Just a thought.
