I’ve just developed a very odd problem. After a few seconds (or sometimes immediately) the slideshow keybindings stop working

No slides switch, and I can’t quit (have to kill the program). Any thoughts on how to debug this issue are welcome, since I have to give a talk in a few days.

You could put a printf down inside the low level key handling routine and see if that shows up

I don’t have any good ideas, in case that wasn’t obvious from the above. :grinning:

@robby Do you know offhand which file I should look in? Otherwise I’ll find it

not offhand; I would have to poke around to recall

Ok, thanks, I’ll have a look

(But Matthew did a lot more than I ever did.

)

Well, further investigation (thanks for the suggestion Robby) tells me that do-key-event in mred/private/wx/window.rkt is never called when the bad behavior happens

Which I think means that somehow the connection to GTK has gone wrong
