ICS Calendar Plugin, popups not working correctly

I have this same problem:

First of all, fantastic product!

I’m sure I’ve somehow messed this up, but everything used to work just fine, now I’m having popup troubles:

When I have “onclick” set, ALL of the popups are immediately visible and one must click elsewhere to make them disappear.

If I change the setting to “mouseover,” things get worse: the first event is “pinned” to the pointer, and stays that way the whole time you’re on the page…hovering over a different event doesn’t change it.

I thought I’d eliminate the problem by turning off popups altogether, but without either mouseover and onclick set, the popups are all visible all the time and there’s no way to make them disappear.

Help?
