I am trying to write my own bitmap editor but it keeps crashing.
Basically I want to edit my owe graphics and the color palette. When
I try to modify a palette it crashes. When I try to copy colors to
the pallet it crashed.

It works when I set the colors to 0
but when I set them to another value I have a problem. What code
should I post and where do I look to try to fix this problem?

You need to run the program in a debugger. It will halt the program
when it "crashes" and show you the line of code that caused the
problem. If that line of code is down inside some library you didn't
write then use the debugger stack window to trace back through the
calls to see what line of your code led to the issue.

Why? Why mess with palettes at all? I'd be tempted to compare 256-
color graphics cards to horses and buggies, but that wouldn't be
fair: in the last 5 years (for example) I'm pretty sure I've seen
more horses and buggies than 256-color graphics cards...
