You wanted a practical example; that what I gave, something that I actually do that would be broken if our multitasking wasn't preemptive. Yes, I could do something else; I could take my hand off the mouse and use the keyboard, or I could scroll up in my review buffer, but that's not what I want to do...I want to stop the scroll using the mouse to read and/or ponder a line or two; then I want to let scrolling continue. I don't want to fool around with back scroll. I don't want to use the keyboard. As I said, its not a great example, as I could change the way I work. But it does show there are differences between preemptive and non-preemptive that can make a difference, and its hard to make a statement like "No one would want to ..." and make it stick. Someone will always want to "..." andy -- andy finkel {uunet|rutgers|amiga}!cbmvax!andy Commodore-Amiga, Inc.
