[Plugin: Event Calendar 3 for PHP 5.3] Calendar Widget Popup

I’ve selected ‘hide popups’ in the event calendar setting screen, however the popup is still appearing when I roll over a date on the event calendar widget. Which line of script can I modify to resolve this issue or is there another to stop the popup from appearing?
