SHAKYBRAKE

Hi All! I installed my Robbins cloth top in MY02 about 2 years ago and since then the corners have been pulling back away from the windshield frame. I tried pulling the top in place and holding the corners down with the screws that hold the rail in place along the inner edge of the front of the top. That didn't work so well as it just ripped the top right out from under the screw. To my knowledge I followed the instructions adequately during the install, but it's always been wanting to pull back and not stay tucked against the windshield frame.Does anyone know how to alleviate this problem?
