- Amrit, I don't know why you are having "ghost" pixels, but I wonder if you are
- allocating the SHR screen with the Memory Manager before you start writing to
- it.

- Ok, here's my suggestion (although you've proobably tried it, this seems to be
- the BEST way of going about it): set the SCB's for each line to zero, then make
- all colors in color table $0 BLACK ($000). Then when you turn on the display,
- it will show only a BLANK, black screen! This is also the fastest way to clear
- the display to black. If you want, you can then fade in all the colors once
- you've drawn everything you want. Hope this helps...
