Because the EditableListBox is catching the EVT_BUTTON for the delete 
button, and not calling Skip, and because of how you bound the event the 
other event handler is called first, (so because it is not calling Skip 
it stops looking for handlers.)  If you want your handler called first 
then bind it like this instead:

   self.imageList_delbutton.Bind(wx.EVT_BUTTON, self.OnDeleteItem)
