Problem with Annotated PHP Manual web pages

There seems to be a problem with some of the Annotated PHP Manual web pages; when I move my mouse pointer over `add note' on the `Session handling functions' (index) web page it does not highlight in the way that the prev', source', search', about' and `next' buttons do. When I press it I get a page which displays a message about `search terms' being undefined. I think the Annotated PHP Manual web pages are broken somehow. I've used both Netscape Navigator on a Unix workstation and Microsoft Internet Explorer on a Windows NT PC, and the result is the same. Also, it annoys me that many of the `Session handling function' web pages are very wide (too wide even to print on 17" wide paper!). To read the notes, I have to fiddle with both the vertical and horizontal scroll bars. John A. Murdie Department of Computer Science University of York England
