Well, I'm using this:

    PUBLIC SUB ListView1_DblClick()


       DIM f1 AS Form

       DIM sTag AS String

       DIM sHandel AS Window

       

       sTag = ListView1.Key

       sHandel = FindWindow(sTag)

       IF NOT IsNull(sHandel)

         sHandel.Raise

       ELSE

         f1 = NEW FTest 'the actual form class of the detail window

         f1.Center

         f1.Tag = ListView1.Key

         f1.Show

       ENDIF

       

    END


    PRIVATE FUNCTION FindWindow(tag AS String) AS Window

       

       DIM w AS Window

       

       FOR EACH w IN Windows

         IF w.Tag = tag THEN RETURN w

       NEXT

       

       RETURN NULL

       

    END


This seems to do the trick for (1) and pretty works at light speed.  So 
all is good.

Re (2)  it's not when the user acts on the main window, it's when they 
minimise the secondary ("detail") windows. That seems to minimise all 
the application windows.  I've tried various combinations of SkipTaskBar 
and Stacking properties but no luck.  I may have to try and intercept 
the minimise button click somehow to see whats going on.
