It sounds like one of your lock cylinders is sticking- probably because they don't get used often, everyone uses their fob. When you turn the key in the door to open, and hold it, the windows will roll down. If you hold it to lock, then they will roll up. I think when you unlock the door, the cylinder does not fully return, so it may just be on the edge of that switching point. When you unlock it, make sure to return the cylinder to dead center, maybe rock it back slightly to be sure. otherwise it may be a defective door latch, in that case I would suspect the driver door since it is the one you are turning the cylinder on.
Does your fob have a red LED light that flashes when you push a button? And it isn't flashing on it's own without being pressed is it?
I think yours may be too early to have the LED- but I have seen the buttons stick and keep activating door locks constantly.
