Will do, but it is a bit difficult to extract. I have found one clue 
though. The valuebox is in a custom composite control, the button is on 
the form in a project that uses the control.  So I guess that within the 
composite control the focus is still on the valuebox.

(Composite control = a custom control that uses a Form with 3 textboxes 
and a valuebox as it's visual representation.)

The more I think about this, the more it makes sense. But it is an 
interesting take on the whole Focus situation. i.e when a custom control 
loses focus then should all its' children also lose focus? I don't know 
maybe that would upset things.

I'll have to build demo from scratch to demonstrate the problem.
