How come when I get a email from someone and there is a link in it I can't click on it?

Your internet/antispy software might have links disabled. Also depending on how they was mailed to you. with the beining "http://" ect. It might not have been made into a link. Simple issue is who mailed it to you vs what it is, and how it was mailed. Some websites ect will mail links and if thier mailer system screws up they put int "If you cant click here just cut and paste into your browser window"
