In the calendar anytime the time changes there are post backs that totally slow down the appointment creation process and give the hour glass and you just have to wait. I understand this is due to make certain the stop time is after the start time. There are jquery ways of doing this to avoid this slow down. I propose this get moved to that method so that we can get items added more quickly.

As a side note if the post backs are related to meeting conflicts than it's just broke as I can schedule meetings on top of each other (which that is my choice to do so again remove the post backs). 

This will greatly speed up the calendar entries and if I am missing something here (e.g. a setting to turn this off then please tell me).
