yes i removed the 4 screws one at each corner and the interior trim drops with the blind in it, mine has both solid blind and a flynet blind, the flynet was the one that lost tension and found if we pushed it open the blind would just hang down, it sounds like the runners either side may have sonething stopping it, maybe try pushing a cotton bud in there with a bit of lubricant on it then work the blind open and closed a few times, mine works like a dream now i have retensioned it, my next step is try the retension the Heki Rooflight blinds although i am not looking forward to doing them
