This may be the thread you wanted:

A couple tips for future reference:
First, use the google search in the search pulldown. The FGRV forum search isn't too good.
Second is give your post a meaningful
title. That helps in 2 ways. The main one is that similar threads come up at the bottom of the page based on those keywords. Second is some people never get past the thread titles.
Regards,
Matt
