Re: st: punaf error, even with version control

[Richard Williams <richardwilliams.ndu@gmail.com>]

Given that -punaf- uses version control, I am a little surprised that 
you are having this problem. Is -margins- not respecting the version 
control, i.e. is it using Stata 12 format instead of Stata 11? If so, 
that would seem to be a bug in -margins-.
