This is from CVS as of 04-Dec-2006.  With "emacs -Q":

M-x man RET printf RET

You get a man page.  Go down to the "SEE ALSO" section and mouse-1 on
"printf(3C)".  Eventually you get the appropriate man page.  OK.  Now do:

M-x mouse-sel-mode RET

And repeat mouse-1 on an item in the "SEE ALSO" section of the printf(3C)
man page buffer.  I get an error "No item under point".

Switch the current (lower) window to show the original printf man page
buffer.  Now mouse-1 on any item in the "SEE ALSO" section just displays the
printf(3C) man page buffer in the other (upper) window.
 
(Interestingly, if I start with "emacs -Q -f mouse-sel-mode", then mouse-1
on "printf(3C)" first raises a buffer-read-only error, then sometimes works
and sometimes does not.  I haven't been able to work out what the criteria
is.  Hopefully this is just a manifestation of the same bug.)
