Yes, the same thing happened to me, good thing you brought it up. It thought it was a computer glitch.
I had the same thing happen in the previous E39 BMW 5 series, I had to use the remote to open the window ( it wouldn't open ).
Please post when you have a fix ( it happen to the right side rear.).
