I agree. I am just starting out on learning OpenGL and am making a terrain generator (bit more interesting than starting with rotating cubes) and wanted to draw a set of axis in my scene. I used glBegin/glEnd because I didn't want to bind buffers and set up shaders just to draw 3 loving lines. I figure it may be slower than the alternative but it me saved a lot of effort and should it cause me problems later on I'll deal with it then.

As I said I'm still a novice to this so if I said something dumb please correct me.

Try setting your texture parameters after binding your texture, like this:

code:

	glGenTextures(1, &TEX_NAME);
	glBindTexture(GL_TEXTURE_2D, TEX_NAME);
	glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, WIDTH, HEIGHT, 0, GL_RGBA, GL_UNSIGNED_BYTE, tex_data);

	// Prepare texture-related nonsense
	glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
	glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);

	glutMainLoop();

I can't give you any reason why this should make a difference but it worked for me on my machine (Windows 7 64 bit, Visual Studio 2010).
