Shift-escape and two screen calibration about titta HOT 7 CLOSED

Oh, just saw the Titta paper is published, congrats! 👍

Yeah, I also normally have a try catch, but in a small test setup the calibration ended up outside my try which is how i found this.

I normally add ListenChar just before keyboard is polled, and then reset just after, so e.g. https://github.com/dcnieho/Titta/blob/master/demos/readmeMinimal.m#L54

ListenChar(-1);
EThndl.calibrate(wpnt);
ListenChar(0);

I didn't know Windows doesn't leak keypresses like Linux and macOS; interesting!

Yeah, they also told me a new SDK should fix this. For a bug which compromises core functionality, I am not impressed by how slowly they responded to this.

I just tested KbCheck() on Windows 10 + MATLAB 2019b and I see the same behaviour, in that keys you press leak into e.g. the MATLAB editor if it has focus. Test code:

KbName('UnifyKeyNames');
loop = 0;
while true
	[keyIsDown, ~, keyCode] = KbCheck(-1);
	if keyIsDown == 1
		rchar = KbName(keyCode);
		switch lower(rchar)
			case {'q','0'}
				break;
			case {'1','1!','kp_end'}
				loop = loop + 1;
				fprintf('Hello %i!\n',loop)
		end
	end
	WaitSecs(0.01);
end

If I run that from the editor, everytime I press 1 I get the print statement but also a 1 leaking into the editor. Maybe you don't use KbCheck or set up in a different way?

Actually we are having serious problems getting past the calibration stage, we have yet to even collect data, I'll contact you offline for some advice...
