I've contributed to putting this thread off course, for which I apologise. In the interest of the OP getting an answer to his question, could I ask that responses from here on be on topic?

And to the OP, I've read and reread your original post and I really misunderstood you -- I see now (that I'm not speed-reading!) that you didn't mean what I thought you did.

Sincere apologies and I hope someone here can help with your query.
