Internet Explorer 7 very slow to launch and run under Vista

I have Vista Home Premium on an intel core 2 Quad CPU machine. The problem is that when I launch IE 7 it just takes forever to load up. Also when I key something into the URL line at the top, my keystrokes are definitely way slow. None of my other browsers exhibit these symptons (Safari, Firefox..)

I looked at some forums & they suggested disabling Add-ons. I’ve done that. Yet same symptons. Any remedy?

I do recall seeing something out there where someone suggested at the Start line typing in a command like: iexplorer – (same flags).

any ideas?
