I know I know evough to be dangerouus, but .......
Hi Jason and Neilo,
.... I just learned something interesting:
(1) It seems, based on my experimentation, that the menu overlapping issue is resolved by changing (to 161 px) the LEFT parameter in only the CSSMenuWriter/cssmw10/menu.css file. I did not change the LEFT parameter (111 px) in the CSSMenuWriter/cssmw0/menu.css file. Despite not making any changes to the cssmw0/menu.css file, the menus appear to be working file.
(2) As I said, I know enough to be dangerous! As I said in my previous post, it would be helpful if there some documentation explaining or at least describing the purpose of the several folders and related files.
I want to thank you both, Jason and Neilo, for your suggestions and your patience with a learner such as I. I am indebted to you both.
