- What I'd like to know is the fastest system-friendly way to
- scroll an Intuition screen around (with scrolling, I mean the
- autoscroll feature). The reason I'm asking this is that I've
- been writing a commodity that allows one to scroll the
- frontmost screen using a hotkey like the virtual window
- managers in X. MoveScreen just seems too slow, I get errors
- during heavy serial load (dnet chokes). Maybe it just can't be
- done, but scrolling the screen with the mouse doesn't cause
- any problems. I already asked this once but nobody gave any
- answers.
