I seem to have encountered a bug where the all day event would be shown on the incorrect dates. I was able to reproduce it using one of your online demos so I wont bother posting code here.

- On the demo page, click on week to switch to week view.
- Double click on Bob's birthday and change the from date to 3/25/2007 and leave the end date as it is (3/30/2007).
- Click on update.
- So far so good. Now click on "Show 24 hours" at the bottom of the scheduler. Note that the appointment for Bobs birthday has moved dates.
