When trying to work with two or more CalendarWiz calendars at the same time, sometimes the browser gets confused between the two calendars.
This problem can happen with all browsers. The problem arises from the fact that any individual browser program shares it's cookies with other windows for that same browser. Cookies are used to keep track of calendar sessions and when there are two calendars open the sessions can get mixed together.
The best solution to the problem is to use two different browser programs such as Internet Explorer for one calendar and Firefox for the second calendar. That way the cookies don't get mixed.
To download a second browser follow one of the below links:
For Firefox: www.getfirefox.com
For Internet Explorer: www.microsoft.com/ie
