From: -X- How, in Tk, can I XXX: A10.D.3. The default for Tk's listbox widget exports its selection as the X selection. There can only be one of these at a time. To turn off this behavior in Tk, use the -exportselection false when you create the listbox. Or, use the option add *Listbox.exportselection false command in the beginning of your script.
