Why won't materials stay aligned on a mesh face?

[Satu Moreau]

I tried the same texture, normals and specular maps on a cube, set to planar the same as I did on my mesh wall, stretched it, offset it some and all three stay aligned. But they refuse to stay aligned on the mesh wall. When I select a different face, the one I was just working on jumps it's normals and specular maps to their previous horizontal offset and refuses to stay at the new one aligned with the texture map.

Not used to this page, not sure why you can't reply to further clarify. I do have them set as separate texture surfaces, but I'm talking about on the same surface, the normals and specular maps refuse to stay aligned with the texture map. I can set them up, line them up, but as soon as I deselect that surface, it snaps back to misaligned instead of staying lined up.

Unless you have designated different faces to have different texture maps, they are all considered one face, with a mesh object.
