windows open key fob

I have a friend with a 2006 Accord, when she came out one morning all her windows were open, then in the mall one day returning to her car she pushed the unlock button on her keys and the door unlocked and the windows opened has anybody heard of this problem.

If you press the unlock button and hold it, all windows and the moonroof (if equipped) will open. If she did not hold the button, it is possible that it is sticking and/or the transmitter is sending a constant unlock signal. If she presses and releases the unlock button quickly, the LED on the fob should go out when she releases the button.
