Every time I am reviewing my hotmail emails, my screen temporarily locks up and I get the following message:  "There was a problem with the Outlook  service (a temporary network connectivity issue that has nothing to do with your computer). Please try again.  If you keep seeing this message, go to Service status to check if there's a problem with Outlook. "  I always have to refresh the hotmail screen.  Anyone else having this problem?  And why?
