Brian, thanks for the quick (immediate) response.
I don't think this is an issue on just my computer though. I'm using an iMac with Firefox 6 but my operations manager for our club uses a Windows PC with Firefox and has the same issue. I'll add events and he always tells me we have no events on the calendar, then I have to remind him to refresh his browser. He wants to know why he has to always do this?
I also have another issue which I don't think is related but in the off chance that it is . . . Whenever I add a new event and save it, about 90% of the time, the page just sits with browser running and never returns to the main page where you can add another event. The only way for me to get back to that page is to clear my cookies. When it does this it IS adding the event to the calendar on my site, but just won't let me get back to the admin to add another event. This problem is the same on IE, Firefox, Opera, Safari and Chrome. I'm running your latest version too.
