I have encountered a rendering glitch that seems to affect WebKit browsers, but not Internet Explorer (go figure!).
If I scroll to the bottom of my event listings page and click the last event, when the popup window appears with the event details, the details and the register button are rendered below the bottom of the page. To view this glitch, the scroll bar has to be dragged ALL THE WAY down to the bottom of the browser window before clicking on the event.
The page I am editing is here.
I think the issue is related to how the "popups" are actually hidden inline elements, and the problem arises when the "popup" is switched on for display. I think the plugin is miscalculating how much space is available in the browser window.
I'd appreciate any tips or workarounds!
