I'm using Drupal 7.15
I tryed colorbox colorbox-7.x-1.3.tar.gz
with the Calendar module calendar-7.x-3.x-dev.tar.gz.
My problem Calendar is working perfectly and when I'm clicking on a date the event details display well.
But when activating Calendar with Colorbox
Administration > Configuration > Date API
when clicking on the event the windows pop-up but nothing is dislayed (except prev, next button and view thing : more details in the screenshot)
I tryed many jquery version (1.4.4 and 1.5.x ) : no succes
Keep ready fore more information.
