Hello, I have had this issue for a long time now and just dealt with it by always reading my mail in IE, which I dislike very much. It's very strange...When I click on my Yahoo Mail shortcut (or access it any other way), the page shows up for several seconds very distorted and totally magnified before it reloads in IE, at which point this is in my browser window: chrome://ieview/content/reloaded.html. I set the page to automatically load in IE because I cannot read the distorted page what-so-ever in Firefox. At one point, it worked for a couple days and I thought it somehow fixed by itself. However, it went right back to messing up. The thing that initially triggered this was that my cat was stepping all over my keyboard one day and somehow she hit a combination of keys to cause this issue. Any help would be much appreciated!
