After my trial of IE 8 I have finally gotten my shortcuts to once again open in new tabs instead of reusing windows.
So here are the ways to do it. Each one may or may not work for you and if you screw something up, don’t blame me. 
Method 1:
I took the plunge and download IE 8 when Microsoft let me know about it via the updates manager and I un-installed it shortly after.
Anyway, at fitst IE 8 seemed to be OK but then it started freezing when I opened multiple tabs.
Then when I clicked an email link, it would keep reusing the same window and sometimes freezing if it wasn’t loaded already. And this would cause Outlook Express to freeze.
