Help. I can't send\delete yahoo mail!

Started 2 days ago. When I open yahoo mail. I cannot click ‘inbox’ to open. I just get a little message at the top of the screen that says ‘loading…’. It disappears but the mailbox does not open. I can open by right-clicking and selecting ‘open’.

But it does this when I try to send or delete also. There’s no way to right click there.

It doesn’t do this in my gmail account. I have cleared cache (complete), disabled add-ons, tried their ‘new’ e-mail, downloaded IE8, downloaded firefox, restarted multiple times, checked mouse options…nothing has helped.

Has this happened to anyone else?
