Working on dash, added buttons, was adjusting colors; In “IMAGE BLEND COLOR” field, in opacity, if it is set to 0, then the serial port will not broadcast a button press from that button. If it is set to as little as 1, it works. Not sure why this would be case, drove me nuts for while;
This is by design since we need to have mechanism to disable the button. Now button disable works by setting it invisible.
