Help with 'send link by email' on browser page

You all are the greatest!! Whenever I've had a problem in the past you've 'fixed' it for me. So now that I have Vista I'm having problems. First, the firewall is constantly turning itself off. Every few minutes it seems I'm going back in to turn it on. What's up with that? But another problem I'm having is that on the internet browser under files where it says send link by email or send page by email...it has been turned off and I don't know why or how to turn it back on. Can anybody please help?? And another annoying thing with Vista..is that recovery disk balloon keeps popping up? What can I do about it? XP had it's problems, but at least I could fix those and find folders on that operating system. Vista everything is 'hidden'. Thanks everyone!
