Hi there! I just upgraded to the PRO version, which also included the 2.0 update, and ever since the tab on my website starts open and stays open even though that option is not selected in the menu. To close it you need to click twice on the button (one time to 'officialy' open it and then another time to close it). This happens with both the cssonly versions as well as the normal ones. I've used exactly the same options and CSS file to make the tab slide, so I'm not sure where this could've gone wrong. For an example, please go to the site.
Any idea what the problem might be?
