Right...yeah at first I ignored it until I found some faces on the inside Z plane of my model that I didn't put there. That area should have been completely hollow, cause by this point I had only begun to reshape a box after deleting half and mirroring it. I hadn't cut or sculpted any poly's so I'm still confused as to how these additional faces came to be.

Anyway I figuire it probably had something to do with that error, because after all those were undesirable results =) I still have much to learn about this tool.
