I have a planar face that is part of a solid body extrusion. For one bizarre reason or another I cannot get this face to show..

I know for sure that it exists because SWX treats the body as a solid and not as a surface. The body has volume and mass, so no issues there.

The face is only selectable when I RMB click in the vicinity and then use 'Select Other' to highlight it. It is not set to transparent or anything like that...

I have tried updating my graphics driver but no joy...

Ideas anyone?
