Hi Jon, fraid I beat you to it, I've just submited a bug on wings sourceforge page.

I was a little concerned because it doesn't import posers .obj geometery files either which is needed for conforming clothing.

It shouldn't really matter what bits of a poser object you choose for export due to the way the wavefront format works. I've written obj exporters and importers and always used poser characters as my 'soak test' as use all the vertex based features of file format, they're big and they're valid.
