Problem with flipped surfaces

Hi everyone,

I am part way through modeling a ship. I exported as obj into Kerkythea and on doing a test render found that some of my surfaces appear to be flipped. The plain coloured material as exported by MoI renders fine. The problem surfaces when I apply my Kerkythea material which seems to render one sided. I don't think that it is an export issue as 3ds does the same thing. I think the problem may have happened following a boolean.

A search of the forum indicated that a "flip" command was available in a beta but I can't seem to find it. Shortcut perhaps?
