Hi Joseph,<br><br>I&#39;m back and rereading the thread to attempt to get a grip on this.<br><br>Just wanted to say that I hope you don&#39;t mind that your initial post has exploded into something else - you triggered a good one though, well done.<br>
<br>I would be delighted to have a peek at your solution to this (admittedly slightly different) problem as I&#39;m sure it would help my own limited knowledge of these complex issues to see something in action, if you wouldn&#39;t mind sharing?<br>
<br>All good wishes,<br><br>Julian<br><br><br><br>
