Window lift keeps letting go of the glass

My front door window regulators don't hold tight to the bottom of the window glass, and separate if pressure isn't applied to the top of the window when rolling down. What works well to give the window lift some grip on the glass?

I used some epoxy on mine. You also want to make sure the window channel is straight and clean so the window moves up and down easily.

Thanks Mike, I'll give that a try and tidy up the channel while I'm at it.
