I removed the update to IE9, so the display issue (the little navigation symbols in each display window; that this thread was originally for) is gone.

Now I have an .stp that I'd like to export to .igs or .sat but there is nothing saved... Will deinstall MoI and reinstall, perhaps this solves the problem.
The .stp has lots of surfaces that I'd like to use somewhere else. If I find no way to import I'll send you the file. but I'll try around some more first.
