I have a combo loaded with some items ( 100, 1Test!, 234, 650, ArAr, Aras) so user can pick one off the list or add one of his own.  When user enters "1", automatically 100 is autoselected.  But since the user wants to enter the value "1" exactly, he deletes the "00" in "100" and tabs out of the combo.  Immediately a strange behavior occurs - As the user tabbed out of the combo, the item with index 1 ie. "1Test!" is automatically selected - which means the user is now not able to add any of his own items as long as there is a partial match for the item he entered.  The behavior is the same with AutoComplete = True/False. 

The fact that it goes by item index is very strange and troublesome for the user.

 Any ideas about how to get this to work correctly. ?
