Brian,
>That fixed part of the problem! The avalible list now populates. The button to move all moves all the items to the selected list and from the selected list all the items can be moved back to the availible list. The move selected(one item) button from availibe and the buttton to move one item from selected do not work. Any idea what causes this ?

It's hard to know exactly what's going on from here, but try this:

1. Open your project in Visual Studio
   
   
2. Open the following file:
   
   C:\Program Files\Mere Mortals .NET Framework 2005\Mere Mortals Framework Windows Forms\Controls\mmMoverControl.cs
   
   
3. Set a breakpoint at the top of the MoveItem() method
   
   
4. Run your project, click the Move button and trace through the code to see what's happening

Note: If you don't hit the breakpoint at run time, see the MM .NET Dev Guide topic "Stepping through MM .NET Code in the Debugger".

Best Regards,
