@Isildur Ahh, I never read that. And thanks, that's a clever trick and shall suffice for the time being.
Glad to help. : )
(By the way, I hope it didn't sound like I expected you to be aware of the other thread. I'm in the habit of frequently linking to previous posts, both because they may contain discussion on the same subject that may be of interest to others, and because it helps make a breadcrumb trail for myself when on some future occasion I'm trying to remember where I posted something or got some info.)
