By default 
          Prop automatically creates a list of programs based on what it finds 
          in the program directory. You can manually specify which programs are 
          displayed in the program list by using the Configure Programs Window 
          which is accessed using Options >  Configure Programs. 
          The Program window consists of two lists, one is the program list currently 
          Selected; unselected programs are placed in the Programs Found list.
          If you are using the default settings then the Programs 
          found list will be empty as Prop will have already added all available 
          programs to the program list.
          
          
          
          To add or remove programs from a particular list 
          simply select the desired program and then click the relevant button 
          (add/remove) alternatively you can double click the desired program. 
          The add/remove all buttons can be used to transfer quickly the contents 
          of one list to another.
          
          When you are happy with your selection please click 
          on the OK button to save your results; hitting cancel will invalidate 
          any changes you have made. By making changes to the program list you 
          will also switch prop from automatic selection mode (if activated). To 
          allow prop to select programs automatically again use the preferences 
          menu.
