It probably has something to do with the fact that every time something 
is selected you are removing all the items from the list and adding them 
again.  So the selection happens and then you delete all items 
(including the selected one) and then try to select it again.  Then the 
mouse up event happens and the native control processes that in whatever 
way it does, and since the original item selected on the mouse down 
doesn't exist any more then it deselects the current selection.  I bet 
if you don't remove and re-add all the contents upon the selection event 
then things will work fine.
