VisibleOnScreen changes immediately after point and fix

My issue seems to be a limitation with VisualHint's Smart PropertyGrid.  The labels are being built dynamically using reflexion to interrogate the components on the screen.  This obviously helps with performance, but means that it is either not possible, or I don't have the knowledge to be able to get a handle to them.  If I was able to do this, I could click on the label and thus activate that row and get a handle to the field control.
