Try changing line 265 to read:
var code = e.originalEvent ? (e.originalEvent.charCode ? e.originalEvent.charCode : e.originalEvent.keyCode ? e.originalEvent.keyCode : 0) : (e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0);
and 266 to read:
if (code === 13) {
I think something happened with a Chrome browser update that broke the original code. Not sure.
