\thispagestyle{empty} not working for me

  My publisher's preferred format is to have the preface before the Table of
Contents, but the ToC should be paginated starting with 'i' (1 in Roman
numerals). Immediately before the ToC I have an ERT box with
\pagenumbering{roman}
\setcounter{page}{1}
but, the second page of the Preface is marked "II", the third page is marked
"i" and the second page of the ToC is marked "iv". How do I control this?
That is, how can I turn off all page numbering prior to the ToC and then
have that begin with "i" rather than "iii"?

  I've looked on the Tips & Tricks page for paragraph numbering and it seems
that \thispagestyle{empty} should work when placed after the title,
"Preface". But, it's not working for me.

  What have I missed?

Thanks,

Rich
