Nissan Repair: 2002 nissan power windows, power windows, alarm system

Question
As long as I am sitting in my car with key in the ignition, or driving, the power windows work nicely, however, when I turn the ignition off and exit the vehicle, the driver and passenger power window goes all the way down. I HAVE NO IDEA WHY. Can you tell me what is wrong? Thanx.

Answer
do you have an alarm system installed on this vehicle?  when did this start happening?  was there anything done to this car before this started happening? i need some more info on this to give you a solid answer.  if you did have an alarm system installed, take it back to the shop and have them double check everything, it may have been wired incorrectly.
