Using Internet Explorer 9 for reasons unknown, my Yahoo mail "Inbox" no longer displays the sender in the "from" coloum.

I have changed from latest back to "classic mail" which did not fix above.
-- unable to indentify the fix!

Can someone please help me for my Yahoo mail "Inbox" to display the sender "from"?

When I use Mozilla Firefox, my Yahoo mail "Inbox" correctly displays the sender in "from" column!
