I started having numerous problems with my email,
I couldn't view and when I tried to click would not let me look at my emails,
continuously making me login and then still not working driving me nuts!
The FIX we found that worked! Yeah!! FINALLY
When you are in your Windows Explorer Browser
Hold down the ALT key on the keyboard
right below the address bar click on TOOLS
Then in the drop down list click on COMPATIBILITY VIEW
Once there make sure the yahoomail website is showing up as Compatibility view On in the settings for this website
This Instantly solved our problem and the email appears to be working properly now, I hope this will help someone else having the many frustrations we were.
If you are having problems on other websites that were previously working correct in Internet Explorer 9 but quick working right when you installed the update of the IE10 you might try this same fix!
Happy Surfing!
