What is the current value of `transient-mark-mode' - not just the setting in
your .emacs?

If transient-mark mode is active and you have an active region, and it
doesn't appear highlighted, then check (via `list-faces-display') to see if
face `region' is actually something noticeable.

What do you see when you try emacs -Q? That will tell you whether the
problem is from Emacs itself or from your .emacs.
