Milkshape/UVMapper texture mapping issue

I'm trying to make some simple boxes in Milkshape3D for things such as crates, filing cabinets, etc. I then export the wavefront obj and name it box.obj. Open up the UVMapper and select new UVMap -> Box. It then gives me a nice texture map for all sides something like the following which is fine cause it gives me the ability to paint all sides differently:

----
| /|
|/ |
----
---- ---- ---- ----
| /| | /| | /| | /|
|/ | |/ | |/ | |/ |
---- ---- ---- ----
----
| /|
|/ |
----

I then save the .obj file and the new texture map file and import both into Milkshape, but instead of each one of those boxes above being displayed on their equivalent side only, that whole pattern above is shown on every side.

Thanks for any help possible
