driver's belt is "sticky."

[B 4 You]

so when i want to get out of my car, my seat belt goes up about an inch, then get's stuck. rarely it will free itself and go all the way. i usually just smack it with my left hand, and it unsticks and goes all the way up without a problem. goes back down fine when i close the door. passenger door doesn't stick at all. i was going to spray a little WD40 on it, but i decided that might be a bad idea because it probably needs friction to work. anyone else have this problem? it bugs the heck out of me that i have to hit the seatbelt/tug on it every time i want to get out of the car.

also, if i don't hit it up after 30 seconds or so, it will get stuck in that position until i close the door and open it again.
