Unfortunately, this problem is not easily solved on NT - it is partly deliberate behaviour that redisplay should be interrupted by new input (so you can type as fast as you want without losing keystrokes, and the display will catch up when you pause). I'm bothered by this behaviour as well, but I haven't been able to work out yet whether NT Emacs is doing something wrong that makes redisplay slower than it should be, or if it is simply that Unix machines are better able to keep up with keystrokes and scroll bar events causing scrolling (maybe because as an X client Emacs is decoupled from the actual drawing work of redisplay, so it completes faster). The only thing you can do to affect the scrolling behaviour (using scroll bars) is to increase win32-mouse-move-interval - this reduces the frequency at which Emacs gets sent scroll bar events, giving it more time to finish redisplay before the next event arrives. This also affects mouse selection of text.

Just a minor visual annoyance, but thought I'd mention it. Ray Rizzuto
