IE8 Win7 links not working


Solid State Member
I have win 7 and IE8.
Links from within threads will not open. They are labelled com when I check their properties.

These links will open in Opera and Firefox.
They will also open in IE8 on my two other machines. XP and Vista.

I have tried just about everything google has thrown up but no joy.

In win 7 it is not possible to uninstall IE 8 and install a new copy because MS do not offer a download and IE7 and 6 will not install in win 7.

I know that other folk are having the same problems.

Any suggestions please?
