Calendar Does Not Pop Up

When I use IE to create an event the calendar does not pop-up but it does when I use FF as a browser...  In IE if I go to join it does work just not in the events area when creating an event... 

I went to boonex.us and it doesn't work on there either....

And this was for 6.1 how can I do this for 7.0??

If you want to remove the popup calendar do this :

inc/classes/BxDolProfileFields.php


• FIND

case 'date':     $aInput['type'] = 'date';     $aInput['value'] = $aValues[$iPerson]; break;

// Change to (2 times)

case 'date':     $aInput['type'] = 'number';     $aInput['value'] = $aValues[$iPerson]; break;

I want it to work...  Not remove it....  Its the one where you add an event...  The one where you Join works...
