Thank you to everyone who responded. The problem is solved. I'm embarassed to say that I mis-stated the problem.
My parent window wasn't getting the event at all. I _thought_ it was, because originally the parent window was the only widget that made an "invalid keypress" buzzer noise - the super-window that all other widgets are added to, and therefore it should get all unhandled FL_PUSH events. Anyway, somebody added another widget that also made the "invalid keypress" buzzer noise. And that widget had overrides of show and hide and the bug was that the overrides were not calling their parent class (FL_Group::) show & hide. So the hide wasn't happening correctly, even though visually the widgets were not there. All this became much easier to figure out when I realized who was getting those events. > > > > This all used to work -- I'm about to start backing out code.=20 > > But any less drastic debug ideas would be appreciated. > > > This sounds like the sort of thing you could try on a regular PC > standalone? > Much easier to debug there than in the target... > > Other than that, I've made roughly similar keypads in the past, and it's > pretty much just worked, so I don't know what to suggest... > > The underlying buttons are the right size?
