"Please log in again"

I guess they stomped on this security threat quick-like.

That's true. Now I realize I had to log-in again this morning, even though I checked the two-weeks button.

I cannot remain logged on long enough to send a blank mail to a friend on my contact list. after logging on, i am immediately logged off and asked to log on again. what gives?

Same thing with me, started this morning, on both wireless and wired lans.

Workaround: doubleclick on the gmail agent in the system tray to start another gmail browser, then switch back to the first browser and quick! send your message.

But it is hugely annoying.
