Gordon, I'm so sorry - I'm stuck tonight. I have this technological problem due to my husband's computer (we share the wireless router), which means I can't access your e-mail address directly form the message board. Usually I can get round this by getting it from the board on his computer when it's available, writing it down (how uncool!) and then e-mailing from my desktop which has all the things I need to attach. Since his is off for repair overnight, that avenue is not available, and attempts with either laptop tonight have had the same snag of sharing the router.
So I'll get those fuller details to you tomorrow, when his comes back (with the problem solved, we hope), or if there's any other problem, you could send a brief e-mail to me at e-address on this post, which bypasses the difficulty.
