Passenger window grabs the rubber

[CoBeerToad]

And seeing as how I have no work to do today, but am stuck at work, I should take advantage.

My drivers window grabs the bottom rubber about 80% of the time and slows it down a lot. Seems like it is putting extra strain on the drive motor so I try to help it, without helping it too much which I think would also cause strain on the window motor. Any tricks to ease this or should I just carry around a can of non-stick Pam with me?

Can't edit the title. It's the driver's window with the issue.
