Created Issue: Animation not working when ModalPopupExtender is programmatically hidden [27097]

I have tried everything I can think of and am beginning to suspect that this is a valid bug. The animation specified for the OnHiding or OnHidden events will not execute when the Hide method of the ModalPopupExtender is called in code behind. The Hide method definitely works in that the popup does close, it is just that the animation does not work.

Please see my thread in the Microsoft forums:
