Is there a limitation on "setWatch"?

Ok sorry ;)

I have a "Original Espruino", it is running version "2v04" "AT command Networking Only"

and this is the function:

function visitorScoreUp() {

g.setColor(0,0,0);
g.fillRect(220,82,320,135);
visitorScore++;
if (visitorScore < 1) visitorScore = 0 ;
if (visitorScore > 9) visitorTextOffset = 0;
else visitorTextOffset = 15;
drawOnBoard({title: visitorScore, posX: 235 + visitorTextOffset, posY: 85, vector: 45, color: colorArray.white});

}

Every button is calling more or less the same function.
