[Message part 1 (text/plain, inline)]

If i keep PageUp or PageDown pressed on a buffer, it does not redisplay the
screen fast enough. Only when I release the key, will it update the screen.
I have had this problem since previous versions of emacs on windows.
Scolling with the scroll bar works fine. I ran emacs with -Q. It also
scrolls fine if I run without graphical interface (-nw).
