As you have found out, ComboBox.Clear will clear all the list.  If you 
just want to clear the displayed name, try ComboBox.Text = "".  You 
may need to include a blank entry in your list of names for this to work.

Setting the ComboBox.Text to one of the names in the list will 
highlight that name when you click the arrow button on the combo box.

Mike.
