Courtesty Windows/Alarm

[JAG]

Hello Everyone,
I've got a 2001 Boxster S... I've got a couple of issues, I don't have a clue about and I hope your collective experience could help me out. I haven't bought a workshop manual yet... I've had the car for about 6 months.

My passenger side window will no longer, well intermitently, open slightly when the door is opened. Sometimes it will, but mostly not. And sometimes, when I have the door open, it will start to freak, and open slightly and close about 4 times. While it is freaking, my alarm will signal twice.

The car locks fine, and unlocks fine from the driver's side lock, or the remote. Just the passenger window....

Also, almost always, my alarm will signal twice when I unlock the car with the remote or the door lock..

Does anyone have any ideas on what the problem might be? Bad sensor in the door panel?

Thanks!

....Joe
