The one reported by -mfx- never was a proper candidate for
that. The marginal effects reported by -inteff- and 
-inteff3- (see: -findit inteff- and -findit inteff3-) are
still proper candidates. I am hopeful that -margins- will at
some point in the future report meaningfull marginal
effects for interaction terms. However, I have no basis 
for that hope other than that with the new factor variable
notation they have all information they need to compute 
those.
