As the title says. I keep getting two windows for outlook login. Even if I close one and sign in the remaining window I still get two email windows and are exactly the same one. If it helps on the home page where outlook.com is (upper left), where it shows if I have email or not I get this:

Outlook.com (1) (1)

So it shows that I have two outlooks open.

thanks for your help, if you can.
