Ok, for those that have been using IE8 and find it slow to open, open new tabs, or open new windows, this Windows Fixup website seems to have resolved my issues, and others. Now my IE 8 is blazing fast...
From the site:
The problem, in most cases, is the presence of IE restricted sites and enhanced security configuration zones, which are generally created automatically by spyware removal software, such as Spybot and IESpyAd. Traditionally, the presence of these entries has been hugely beneficial, offering protection against malicious software. However, Internet Explorer 8 includes new security measures that may obviate the need for these entries, and the browser can suffer a tremendous speed hit in their presence.
So, here is the link, Fix IE8 Speed
Basically your installing an INF file that removes all Internet Explorer restricted sites, enhanced security configuration zones and trusted sites.
I was about to go back to IE7, now I am very happy.
