May be you need 'Always One Selected Value' in the listbox for that field. Select a value from the list box->right click->general tab -> check 'Always One Selected Value'

You can lock a selection by right clicking the listbox and choose the option Lock. But you can't lock a selection in the listbox and choose another value in the Current Selections box. Only the buttons still work to change the selection.
