Hi Eric
There was a good sollution in this newsgroup from Jeffrey Tan,
Someone cleaned it up.
There stayed another sollution from Jeffrey, describes the problem good, but
gives not such a nice sollution.
After that in a good discussion wherein I was involved a Billy, Jeffrey
changed his sollution to the right one.
That sollution is still partial in this newsgroup on 29-8 too but only some
end thread OT discussion.
I thougth it would stay, so I could find it on Google, but someone has
cleaned it up.
Sorry for you,
I d' nt have it now and d'nt remember it exact and I said to someone to look
something over before, so I do that first.
I placed Jeffreys name in the subject, maybe he sees it and has it still so
he can repost it.
Cor
