Martin is referring to the option found under ...

Control Panel --> Display --> Effects -->"Show Window contents while
dragging"

I have this turned on in my system. When I turn it off, the window only gets
repainted when the mouse button is released. This just akes the flicker hard
to see since it only happens once per resize. When the option is turned on,
the repaint occurs *twice* for each column or row of pixels exposed or
hidden (using CS_xREDRAW styles).
