Hello. Does anyone know why I would have trouble using allegro and plush
to do 3d and many bitmaps at the same time? What I'm doing is:
  - setup 640x480, 8bit graphics.
  - make sub bitmaps for:
      -3d display
      -button bar
      -statistics display
      -inventory
      -etc
  - also make separate bitmaps for all of the above (for some bizarre
    reason, I have to make, say, a 320x200 bitmap AND subbitmap, then
    have plush render to bitmap, then blit to the subbitmap, then blit
    the 640x480 to screen memory.)
  - load the button bar .pcx, the statistics .pcx, etc.
  - make an optimized palette with everything w/ plush
  - convert that to allegro palette.
  - set the palette

In my main loop, I do this:
  - render to the 3d bitmap.
  - blit the button bar to the button bar bitmap.
  - add the text to the bb bitmap
     (repeat for all displays)
  - blit bitmaps into respective subbitmaps of the hires 640x480 screen
  - vsync() w/ allegro
  - blit 640x480 buffer to screen mem
  - get user input         \
  - make AI choices         >  (actually beginning of loop, but hey...)
  - update positions       /

So, after I do all this, for some twisted perversion of logic reason,
the only thing that actually shows up is my 3d window...
Can anyone help me on this? I'll gladly email or post my source, but I
think this post is gonna be long enough without it.

  I'd be really grateful for any ideas that *work*, and somewhat grateful
for the ones that point in the right direction :) Thanks in advance,
everyone!
