Dan says: "Anyone care to venture a guess why HomeSite requires the full attention of my 1.8GHz Pentium 4 whilst scrolling and, worst of all, still responds sluggish as hell?" Woah, he's right. I get the same thing (though my processor is 1/3 the speed). Wacky. I imagine it has to do with the color-coding, though this has been a feature (albeit, less-sophisticated) in previous versions without this effect (as far as I know). Hmm...on second thought, it happens even on .txt files when there is no color-coding going on. Curious.
