IE8 wont save history url?

I stupidly installed IE8 on my comp and its alright except for the fact that i cant get it to save my URL history. In the address bar the little arrow to the right usually is clickable to view a quick list of sites you have typed in, well its not working and im getting tired of retyping sites in all the time. I also notice its reseting itself when i restart it, like i get the "good job you upgraded" screen everytime i boot up instead of yahoo....Im thinking of downgrading back to 7 but if someone can help me fix this id appreciate that much more. Thanks. how do i get the url to save in the address bar?
