Dennis,
 Many thanks. I solved the problem by adding a PostMessage() command - see 
below.
Richard.

   // get the window handle of the other instance's main form
   //(according to its class name)

   HWND mainFormHWnd = ::FindWindow( "TMyMainForm", NULL );

   // added the following line to show main form if running in tray
   ::PostMessage(mainFormHWnd, WM_SYSCOMMAND, SC_RESTORE, 0);

   // still need the rest if program running 'normally'

   // get the main form's parent window handle (we'll assume mainFormHWnd
   // is not NULL, since we wouldn't even be here unless another instance
   // of the application were actually running)
   HWND hAppWnd = (HWND)::GetWindowLong( mainFormHWnd, GWL_HWNDPARENT );

   if(::IsIconic( hAppWnd ) )
   {
    ::ShowWindow( hAppWnd, SW_RESTORE );
   }
   ::SetForegroundWindow( hAppWnd );
   return 0;
