Jasper,
One of our more advanced TW developers found a way to control button functionality through the use of jQuery and the Expression widget. If you add the below jQuery and reference the correct button ID, you can alter how it works on the client side. Something else this developer found was that using a Value Display as the "button" (it has a Click event) was easier as it doesn't have Hover event to work around. If using the Value Display Click, then no expression is needed.
$('[id*=button-32]').on('touchstart mouseenter focus', function(e) {e.stopImmediatePropagation(); $('[id*=button-32]').trigger('Clicked'); });
Let me know if this helps, or if you have found any other ways around the issue.
I'll post this same message to the Community board.
Thanks
