Spacebar as a pause button not working

Not sure i follow. the name in the keybind is "on_keycall_PAUSE" but so is the function name..... I do see that non-HD is a lower case "pause" for both bind and func name.... Why would this matter?

on_key_pause and
on_key_PAUSE

are different function calls. The code must match what is in the handler file.
qtdragon uses the lower case one, qtdragon_hd uses the upper case one.

Since I can't see your handler file to confirm, I am guessing this is the problem.
Can you confirm they are the same case and/or post the handlerfile you are using.

OK, I figured it out..... When I run a file, it is like focus is lost and pause and space don't work. If I click on any page button at the top other than "Main" while running a file, the pause and space work. Seems like a focus thing.
