Yes. Overwrite the Preamble definiton by defining a replacement (maybe
empty) in your copy.
FYI: LyX 1.6 has a new "AddToPreamble" tag for cases where you don't
want to over-write but just want to add something. If I'm remembering
correctly, I found I needed the tag somewhere, so added it.
However, in the above case it is important to replace the Preamble.
Otherwise the double occurence of \newcommand{<command>}{...
triggers a LaTeX error.
Yes, sorry. I should have been clearer. I didn't mean this would have
helped Steve, in this case.
