hi, i am new to allegro and thus the following questions are very
basic, but i would be very appreciative if someone would lend me a
hand:

after drawing an 8 bit sprite in photoshop, i save it as a pcx and
read it in grabber, grabbing both an rle_sprite and a 8 bit palette
from the file.  i use the palette and sprite in my program, and it
displays fine, however, when i grab a new 8 bit rle_sprite, that
although not using any colors not in the palette (obtained from the
first bitmap), it displays with messed up colors.  

i guess i need to know how to make all the sprites use the same
palette, and not just the same colors... and also, my sprites
currently display as an entire box - the docs (yes, i've read them
:-)) indicate that masked areas are to be of color 0 in the index.
does this mean that i should put some random color i never intend to
use in my program into the 0 position, and color in the masked areas
with it?

obvious i have little idea what i am talking about, but i'd like to
think that that's because i just started fooling around with allegro a
few days ago. :-)  i suspect i'm doing this whole palette/sprite
editing thing the wrong way, so if someone can tell me a better way to
do it, i'd really appreciate it.  thanks!
