I received the answer to my question about the buttons. I’m not sure what the problem is caused by, but was given a number of suggestions. One of them involves using the posting feature of NetNewsWire. Since I am a registered user of the program, this is a satifactory solution. Also, a couple of browsers that do work were given. Brenna (the person who responded) said:
You could use Mozilla 1.3 or higher, Netscape and Firebird
(Firefox) and you’ll have the buttons.
Very fast response to my “problem” … I like that.
