Are you very sure automatic hyphenation isn't working? It may just be
that TeX is able to find good line-breaks for your text without
resorting to hyphenation, in which case it won't bother.

One way you could test this is to deliberately use lots of long
words, along with narrower-than-usual pages; then you're more likely
to see hyphens being inserted.

Another option is to (temporarily) add the declarations

\pretolerance = -1
\hyphenpenalty = -100

at the beginning of your document; this will encourage TeX to
hyphenate *much* more frequently than usual. (The normal behavior is
to try and set the text without hyphenation if possible.)

If you still don't see any automatic hyphenation under these
conditions, then I'd guess something is wrong with the configuration;
a short example document, along with the log file from running it,
would help in diagnosis.

HTH .... JK
