Our last outing our MW jumped out of the track. I pulled the 4 corner screw caps off the outside beauty frame, then removed it. I used a very small straight screwdriver to pop them out. Then after reseatting the MW into the track I got a piece of wood, but any thing will work, that was about 23.5" x 1.5" in size. I put this under the upper shelve brace wood. This will keep the MW from popping up high enough to jump off the track again.
Hope this might help others with the same issue.
