   What does your "do something" do?  If your handler manipulates another
field, you will run into problems because the current selection will become
unselected.  If you are doing this, the way around it is to get the current
selection... save it... do what you have to do... then reselect the original
selection.  I must warn you, it can be cosmetically unpleasing.
