Scroll bar to the right when I click to read an email.

Are you using webmail or a client email like outlook, outlook express etc?
If it is webmail, what is it? And what browser do you use?
If it is client mail, please provide type and version like windows mail, outlook 2010 etc

I am only using Hotmail, nothing else. And I am using Explorer 9 as my browser. Another thing it does, the more I reply using the same email. It starts to get wider, and wider. Meaning, it goes too far to the right of the email. I have to use the bottom scroll bar to go over to the right in order to read it. I just noticed that. I never have a scroll bar going up and down to the right side when I go into read an email. But it is there when I reply to the email. Hope this helps. I don't mind not having the scroll bar to the right, but what gets me is that I can't read my email unless I use the scroll bar at the bottom to move it to the right. ? Got me!
