Oops, misleading header: wish I could amend to to "...not working as in previous versions"

In the latest Phex, setup asks for shared directory, but browse-to option are limited to a mysterious "Shared Files" folder. I would like to specify a full pathname and it won't permit it. I canceled, then went to the "Library" tab and tried again to browse to or otherwise set folder, and same problem. Why the restriction? Is there a way to at least allow me to type a full pathname? I used to be able to do it, with earlier versions.... Must I go back...?
