Just out of intrest, when you roll down the windows, are you then leaving the car alone? I believe it still applies the regular automatic re-locking, so after 30 seconds or so of not interacting with any doors, it will re lock and activate the alarm.
I usually wind down the windows upon approach, and then pop the door open whilst I wait for it to cool a little more, saving the re-locking and promoting a little more air flow.
