A known bug that has been fixed. The function called fDoNM_RCLICK needs 
to be as below...

    sequence xy
    atom keys
    integer lRealId

    lRealId = fetch( lParam, NMHDR_idFrom )                     
    if lRealId != 0 then
        lRealId = getId( fetch( lParam, NMHDR_hwndFrom ) )
    else
        lRealId = id
    end if        
    xy = getPointerRelPos(lRealId)
    keys = getKeyMasks(0)
    VOID = invokeHandler( lRealId, w32HMouse, {WM_RBUTTONUP, 
xy[1],xy[2], keys} )
    return {kReturnNow}
end function


and the routine 'getPointerRelPos' should be ...

global function getPointerRelPos(integer pId)

    if validId(pId) then
        return getPointerPos() - ClientToScreen(pId, 0, 0)
    else                
        return {0,0}        
    end if

end function
