when you put your mouse over the link it should show where the link is going on the bottom of the ie
does it show that? I think the actual link information may be getting blocked on the way in rather then not being used correctly to open the page.
i know you have done at least some of this before but do it all again
and try disabling your firewall and if that doesnt work uninstall your virus protection. You can install it again afterwards but that can be what is blocking it.
try this in your internet explorer
first go to tools / windows update
do all the updates they suggest
then go to tools / manage add ons
disable every add on that you are not sure what it is and absolutely need
then tools / internet options
under general tab
delete all temp files and cookies
under advanced tab
restore advanced settings
reset to defaults
