Thanks Ray. I'll try your suggestion when I return to my office and will let you know how I fare. BTW, I really appreciate your quick responses to my issues. I'm mostly working under tight deadlines (who isn't?) and often need trouble-shooting resolution quickly -- so you're a much appreciated life saver in my case.
