This may not seem like the same problem but it may be...I couldn't even get a texture on a cube (not very ambitious, but I had my reasons). I made the UV map from the object, did my decoration thing, tried to apply it and the texture was suddenly smaller than the original cube and ended up with the flattened texture going on the original cube but not covering it completely, but actually looking like the colored UV map replicated as a small texture on the cube instead of covering the cube (if that makes any sense) with white in the spaces of insufficient coverage. I'm a UV Mapping drop out, bookmarking for enlightenment. :)
