Yes, sorry - I meant \boldmath, not \boldsymbol.

This is exactly my set up, too ...

Well, unfortunately, not so on my set up. Seems I screwed up something
along the way of converting the LWFN fonts, although so far, I did not
notice any irregularities, until this \bm thing.

Well, neither nor. I do have the expert fonts, and I do have the
Expert option. So there must be something wrong with my configuration
of the expert fonts.

By the way, lucimatx is available from pctex.com free of charge for
those
who purchased the lucida fonts from Blue Sky. I think it's worth it.
