Thanks for the note about load creating a bitmap in memory.  I guess I
was inadvertently creating a memory leak.  
Man this prob is annoying me.  I tested the loads like this:

if((message2 = load_bmp("win.bmp",message_pal2)) == NULL) {
	cout << "Error loading bitmap win.bmp" << endl;
	game_over(circles);
}

and

if((message1 = load_bmp("player1.bmp",message_pal1)) == NULL) {
	cout << "Error loading bitmape player1.bmp.  Exiting!" <<
endl;
	game_over(circles);
}

and so on.  Nothing is printed to the console so I am guessing it
initializes the pointer correctly.  This is leading me to believe that
the problem is in the blit function.  I don't use rhine, I write it in
ultraedit and compile at the prompt.  I have been looking at the html
docs that came with allegro for function info.  About rhide I can't
get the stupid thing to even compile a hello world program  I did
however try loading it up and adding allegro.inf and looking through
the help file.  It's the same stuff that's in the html docs.  This is
really innoying.  Only idea I have at the moment is it might have
something to do with the palettes, but I don't know what.

Any more ideas anyone, keep am coming.
Thanks for your help
