Oops, Helen is of course right in that you should use First and not Open. I
do this all the time in my own code and I never use Open myself, just when
answering you - sorry for that stupid mistake. The difference is that
Prepare is very time consuming and I think 500 prepares is more than enough
for it to be visible.
