This is my 3rd BMW in a row with driver's side window problems (E36, E46 and now E82).
It only happens to me when the window is fully down and I trying to leave the car and roll up the windows. Passenger side closes, but driver's side goes up half way and reverses.
It seems to take a handful of times holding the switch (not one touch) to close it.
It happens almost every time, but I've never tried to close it while driving. I suppose that explains how a software change would fix the problem.
