Please see http://www.howtocreate.co.uk/jslibs/ for details and a demo of this script
Please see http://www.howtocreate.co.uk/jslibs/termsOfUse.html for terms of use
To use:
Put this in between the tags:
You can now run the calendar using:
If you use inline events, this script can position the popup as close to the mouse as possible:
