Repeated Log-In

I've had to sign back in 4 or 5 times today even though I've left the same window open (and haven't cleared my cache or anything).

Anybody else having this problem or am I as unique as I think I am?

Thanks. I'm trying that.

Had a hellish time logging back in. When I put my user name & password in the screen in the upper left corner, it did not disguise the password. Then took me to the you've made a mistake log-in screen.
