We had the handle for the shower door come off the panel closest to the shower head twice. I finally put it back on with some Gorilla Glue and SO FAR it has not come loose. We do put two of the spring loaded curtain rods in the track now also JUST INCASE the latch and handle come off again and the DW also throws a rug over the tub and bottom rails to make sure the doors do not slam open and closed if moving and my glue job does not work.
Have had no problems since I Gorilla glued the handle back on so wish us luck!
