Okay... I'm in here enough to pretty much have the whole Login sequence figured out.

But I had something happen earlier today, and I'm wondering if anyone else has experienced it.
The system normally fills in my email and password information automatically.
I rarely even look at it anymore, before hitting the Login button.
All of the sudden: I got an "invalid email address or password" message pop up!

I dutifully went in, and manually typed the email and password in: just to make sure... no difference!

I gave it about a half-hour, and tried it again... everything is working fine now!

Has anybody else seen this pop up?
