Red book 7th ed says:
"For OpenGL implementations that do not support version 2.0 or greater, both width and height must have the form 2^m + 2b, ... For OpenGL implementations supporting version 2.0 and greater, textures may be of any size."

My card support 3.3 but non-power-of-2 dimensioned textures (e.g., 480 x 480) don't come out right. Powers of 2 are fine though. My textures are in bmp format if that matters. Any idea why?

Thanks in advance,
