-version- is not a time machine, so I am not surprised that
that will not have a big effect. With this type of problem it
often helps to rescale the variables so that the sizes of the
parameters are roughly similar. Having said that, -margins- 
is the new command for marginal effects, so in the long run 
it is probably a good idea to learn that command.

Hope this helps,
Maarten
