Windows Vista Opening Links

Hi all, I am just wondering if anyone can help me with what is probably an easy fix. For some reason I can't open links from anywhere except my web browser (links in outlook for example). It is frustrating, the message I get is that I have to set an association. Also for the sidebar the same thing. When I try to open get new gadgets it says the same thing. Its a small thing but it is driving me nuts so please help me.
Thanks,
Paul

Make sure that Internet Explorer is checked as the default web browser.

 

If your not an IE user: set the default browser this way:
