I posted my results with the beaded window seals on 10/10/09 in this forum. The same thing happened to me! The windows will not go past the seals, as the metal at the bottom of the window catches on the seals. If you try to force the window past the seals, bad things happen......don't ask how I know! I got mine from "Classic", and I'm not impressed. I'm wondering who makes these that actually work as they are intended?
