Yep, sorry. I was busy "revising and extending my remarks."Looks like Samclem edited the post to add the other paragraphs. You probably hit the quote button while he was doing this.
For whatever reason, my spellchecker (in Firefox) doesn't always catch typos when I am making a new post. When I submit the post and go back to the thread, the typos are identified. So, I sometimes re-open the post to fix it. Well, heck, while I'm there another thought occurs to me, and the typing begins . . .So, I'm, blaming Firefox for all of this.
