//		The APCI_DoPostBackOverRide is a function that is run on the Windows.Onload event to
//		override the standard Micrsoft function for DoPostBack and the Form OnSumbit function
//		DoPostBack calls on the page will call APCI_DoPostBack
//		The Form OnSumbit will call APCI_FormOnSubmit
//
//		Why: We would get errors when a user changed the page while waiting for the page reload
//
