I am blitting text to the screen in an application I am writing.  Some
users will have old CGA displays and get snow when text is blitted.
Could someone tell me the technique for preventing the snow?  I
remember that it is a matter of waiting for some event to occur, but I
never learned the details.

Thanks.
