Some paint programs store less than 256 palette entries in a 256-color bitmap, but the code always assumed there were 256 palette entries there. You can imagine what problems that can bring. That's the only update this time. Here' s a small update for the site. Now you can download source code, executables, and bitmaps in convenient zip files.
Life is good.
That's about it. Comments are welcome, but let me say one thing. This is happening waaay too much. Debug your own code. I will, however, be happy to help you if the code from this site doesn't compile on your compiler.
