problem(s) after opera upgrade

[jb_daefo]

the latest opera has caused 1 >> 2 problems here
(had to post from Firefox...) details below
..................
problem 1 )) the prior version shows the link hovering
when the mouse is over a link, showing what the site
would be when the link is clicked. GONE. slows browsing
down considerably. An extensive google search failed
to resolve ( due to my lack of expertise on what that
propery of html is called (maybe) )
................
problem 2) I attempted to fix that with various preferences without
success. Suddenly, all the BLUE is gone in daemonforums
and links do not work (like , I could no click on "forum tools"
; it had no effect; so I had to log on with Firefox.
... do not know if that would be fixed with a reinstall or not or
what caused it. ANYONE KNOW?
.....................
this is the first site I've used after attempting to fix the first
problem above so I do not yet know how many sites are affected
by the latter problem.
