After shipping my MAME controller back to the manufacturer I was presented with a straight up replacement of the existing Plexiglas top and essentially trying it again as is. I was also given the option of anchoring the Plexiglas in place with several tiny black screws:
After mulling it over for a day I decided to go ahead with the screws. This way I know for sure that the issue is not going to occur again. My current control panel on the cabinet has these black screws on the surface and it doesn’t take away from the looks of the panel at all.
I’m hoping that I can get the panel back by the end of next week. I’m itching to tear out the old panel and begin mating up the new one to the cabinet.
