I'm having a problem that I can't seem to solve, partly because I'm at a loss for what has gone wrong.

I've created a mesh in Blender 2.65, applied material groups and UVMapped it.  I can apply a texture based on the UVMap in Blender and it textures fine, everything is where it should be.  However, when I export as an .obj file, then import to Poser, something goes wrong.

The object imports and appears with its material groups intact.  However, portions of the UVmap seem to work properly while other areas of the obj seem to have somehow twisted the UVMap so that textures are out of placed, skewed, or otherwise deformed.  I've remapped the mesh twice in Blender, exported new maps and .obj files, imported again into Poser 6 and it the same error occurs.

I cannot find anything wrong with the mesh and this represents 2 days of work that I don't want to have to scrap and start over.  I can post images if that would be helpful.

Again I'm using Blender 2.65 and Poser 6.  Any suggestions or ideas?  Anyone have any similar problems?
