First I allocate the list with glGenLists. Then I build the actual list commands by starting with glNewList(dlMyList, GL_COMPILE), and ending with glEndList(). But for some reason, it doesn't do squat with the display list. All it does is render to the screen anyway, and any subsequent calls to the display list draw nothing. Besides non-opengl code, this is the only gl code that is inside of the list:
	// Specify filtering and edge actions

	glTranslatef(-1+x, 1+y, z);

	float r = ((float)Image->Width / (float)DesignWidth) * (float)2.0f;
	float b = ((float)Image->Height / (float)DesignHeight) * (float)2.0f;

	glTexCoord2f(0.0f,0.0f); glVertex3f(0, 0, z);
	glTexCoord2f(0.0f,1.0f); glVertex3f(0, -b, z);
	glTexCoord2f(1.0f,1.0f); glVertex3f(r, -b, z);
	glTexCoord2f(1.0f,0.0f); glVertex3f(r, 0, z);

Any idea what could be causing the problem? Do you need any more information?

Nevermind, I fixed it. I was trying to create the display list before I was supposed to, causing the list to be invalid (and thus the function ignored). Everything is working fine now.
