- This is news to me; if you are updating the top window, you can use
- raster copies (because your work area is not obscured by anything). This
- makes it a trivial task. If you are not the top window, though, you have
- to walk the rectangle-list and redraw all kinds of little things. This
- takes some time... Only updating the top window is more efficient. It
- may not be more desirable, but then again it might be. I often shove
- the mouse out of the way when I'm typing. If my output goes to the
- window the mouse is on, there is a pretty good change I'll knock it
- out. Or perhaps the cat will jump on the computer table while I'm
- typing, or someone will bump into the table, or whatever. The point is
- that this could be an annoying/dangerous practice.
