Question about Bitmap Display (Win32Lib)

Hi all,

Just a quick question. I'm using Win32Lib to load
and display bitmaps directly to the screen.
Basically, I'm writing a screen saver. The problem
is, the bitmaps aren't displaying properly. They
seem to be trying to use some common palette, and
appear to have some of the colors "merged", looking
very low-quality.

Here's what I do...

1) Load the bitmap using read_bitmap (for a few
   reasons...)

2) Convert the bitmap to a Win32-compatible form
   using Win32Lib's routines (I forget which one
   exactly)

3) Throw a black bitmap, stored in a pixmap, up to
   cover the screen

4) drawBitmap() to the Screen control

5) Destroy the bitmap object

6) Loop back to (1) with the next filename to load

So far, it works somewhat (long run times lead to
inexplicable crashes, I found some suggested
adjustments to the Windows registry that I'm going
to try.) It's just this one little thing that really
keeps it looking so amateurish (it is, but still....)

Any suggestions?
