Thanks for this, Margaret.  Very much I appreciate your help.  I would have responded to you on either my own blog, or yours, but Firefox won't allow me to do either.  Yet, for some strange reason, on some other blogs I can post a comment.  '

Tis a bafflement!  :)

 Can anyone please suggest what browser should I use, other than Firefox?  Firefox is giving me no end of trouble.   Thank you in anticipation for your suggestion.
