Hi everyone. I've got some sort of strange problem with Carrara and a simple boolean operation.

Please - No laughing. I'm using Carrara 3.0.4 under Windows XP.

I took a primitive square and cylinder. Subtracted the cylinder from the square.
Looks great in Carrara. However, In UV Mapper and Poser 7 the exported OBJ of this boolean object looks like crap.
Some of the sides arent visible In Poser 7 and UV Mapper and the circle cut isnt clean like it is in Carrara. I assume this is a problem with normals?
Is there anyway to fix it.
Its pretty frustrating.  :(

The attached image show pics from top to bottom in Carrara, Poser 7 and then UV Mapper.

Help!  :)
