I log in once every 7-10 days with my Hotmail address.  Each time Hotmail/outlook requires a verification code.  I enter it, then the next screen makes me log in all over again.

When I type my first email and click send, this is what I get:

"Please sign in again. To help protect your personal information, we periodically sign you out (for example, after 24 hours or when you sign in to a different account). "

I try saving my email to a draft, but it will not save.  I log out and resign in. I'm not asked for the code at this point.  Now my email  must be rewritten, as it is gone.  
If I log out and go back in throughout the day, I'm not asked for my code.   It will happen all over again on another day .

It happens on IE 10  and FF 24.0.

I use windows 7 on my Dell desktop computer.

Recently removed Kaspersky and installed AVG 2013, BUT this problem has been going on since you folks switched to calling hotmail "Outlook.”

Ideas?   -HOW to stop having this occur???   Thx U
