My dad is having an issue with his browsers. The problem occurs no matter if he uses Explorer or Firefox. On his yahoo news page there is weird text like Axdo FgrO next to the lead story and picuter and the links to other stories are not working. If you navigate to a page that should have a background color, there is no color. Links are also not appearing where they should be. For example, on the apple.com store site the hand appears where there is a link and you can click on it, but the actual link icon (blue and says select) is not visible. We've tried changing color settings, and the box is checked to allow sites to use their own colors and fonts. Any help is appreciated.
