DatePicker - not responding to any clicks

DatePicker - not responding to any clicks


Why in IE8 is the datepicker not filling in the target input box with
the date picked from the calendar?
It works ok in Firefox? I've actually copied the example code off the
datepicker demo.
The strange thing was I tried it in IETester for IE6 - didn't work,
IE7 and IE8 did work. So why would it work in IETester but not in IE8?
