- Not really. What is happening is that the copper is short of cycles when it
- approaches the right hand side... meaning it can't keep up with the
- monitor scanline. It starts shortcutting on stuff. You can fix
- this 2 ways. Use moned to cut down the cycles (TOTCLKS). Mine is set at
- 76, which the the extreme point where the sprite does not dissapear at
- 640 pixels wide.
- Or, as Mr Hagen suggested a few days ago, use the pointer prefs program
- to move the pointer to the extreme right of the buffer. If you use
- Iconian 2.96, you can even go all the way to pixel 63 (64 pixels wide).
- This, of course, will only fix the default pointer/busy, and not program's
- custom pointers...
