I am guessing that at some point you changed the screen width setting so try this: go to your mail, then options, general preferences, messages, change your screen width and save. Now this does not work for all of them, sometimes they just come through wide for no aparent reason.

i'm additionally having a concern viewing some mail. I save getting blunders code 14 and 15. No clarification from Yahoo of what this implies. i'm nevertheless waiting for a respond from yahoo. all of us understand what this implies ?

change the text size to a smaller size.If you are using IE 7 then go to the top right corner.Click on Page>Text Size and change accordingly

View, text size, large!

make your screen resolution bigger
