- I obviously missed that last part about th 32-63 colors
- being set to black. What I told you will create the shaded affect
- but assumes that you havn't used colors 32-63 in the background.
- In order to deal with that problem you will have to either alter
- the screen info directly by peeking and poking in the planes or
- grab a portion of the screen using Get Icon and alter that data
- but regardless, I can't see any simple solution to your problem.
