Thanks for the replies folks! It confirms for me that in order to overcome this minor problem one has to do some extra manipulation. I was thinking maybe it was there but I couldn't find it.
I'm not at all familiar with the way this ebook conversion operates, but it seems that a simple "Save As" (to modify the name) is not in the cards. I mean that's the way you do things with image manipulation, word-processing documents, etc. Seems odd that this simple operation isn't available for ebook manipulation.
As far as getting public domain books here instead of at Gutenberg, OK, I'll try that.
