the problem relates to settings that have changed
While in Yahoo e-mail I used the ctl key and the scroll wheel to enlarge the font for readability. Now when I bring up Yahoo e-mail the pages are all large font and bold. Sometimes they are so big that not much of anything really shows on the screen. Using the ctl key and scroll wheel will not reduce the font size.
