Hi,
    Is it better (mainly faster) to use ScrollWindow or ScrollDC to 
    scroll content of a windows, in either case SetRect has to be used to
    set the scrolling region.

    Also, when scrolling is done fast the screen update is laggins a little
    bit, i.e. new information overwrites the old information before the 
    screen get's a chance to move, in order to avoid this UpdateWindow()
    has to be called between consequitive Scrolls, which tends to be 
    rather slow, any suggestions, solutions to the above.

Thank you,

gary
