Evolution: problem with "Help" function

[robin@cosby.demon.co.uk (Robin Cosby)]

I've installed "Evolution" (standalone version) via Debian "Woody" on my
PC (kernel version 2.4.19) and all seems to work well, except for the
"Help" function.

The only item on the Help menu to produce a response is "About Evolution".
I've installed the packages gnome-help, gnome-users-guide, gtkhtml and 
scrollkeeper, as suggested in various postings that I've found by trawling
Google Groups, but to no avail.

Outside the program, I can access Evolution Help from /usr/share/gnome/help
/evolution/C, with the aid of an editor.

Any advice will be greatly appreciated.

TIA
