I had a single instance of the module on the entire website.
I am central standard time, english language
I had pulled up a fresh "Add event" page, with no events yet added. The very first thing I did was click the icon for start date, but that was the end ofthe road. It literally froze up my entire IE explorer and I had to go through task manager to reboot IE. Not able to reproduce again, but I sure had no problemt the first time around. Will inform if any else is seen.
