S14 window falls off track repeatedly

[2.0-TURBOcoupe]

Ok so about a month ago my driverside window fell off track...no biggie. snap off the door panel put that bad boy back on track and im off and rolling again...NOT THAT EASY.... after rolling the window up and down 3 times it fell off again. So this time I take a little more time messing with the window. I put the window back on track roll it up and down a few times watching for any problem that could be causing the window to fall off track...Nothing...put on the door panel and damn if the ting doesnt fal of again. I put it BACK on track and grease the piss out of the track and the slider. Still No Bueno. Im really at a loss with this thing and if anyone else has had a problem similar to this on an s14 please let me know HOW IN THE HELL YOU FIXED IT.
