I"ve been having a couple of problems with the calendar plugin, but only on Safari (version 6).
The problem is that when moving my cursor around in the calendar area on the page that's displayed by the plugin, I often get flashing from the whole area. Additionally, sometimes the buttons aren't working, specifically the ones to move from month to month on the calendar.
I had someone look into it, and he found that the calendar page was missing an object...some of the time, indicating it's probably a caching/page load order issue. He found he was able to get "TypeError: 'undefined' is not an object (evaluating 'page.start')" in calendar.js line 4, but couldn't reliably reproduce it. Again, this is only happening in Safari.
Do you happen to know of any potential solutions to this problem? It's been happening on this site: http://grandave.mere.li
Any help would be greatly appreciated.
