Does Easy Social time out when typing a long email in mass mail?

When I'm writing up a memo to members in ES mass mail, I find that Easy Social has timed out when I hit the send button. It then sends me back to the login page which then upon logging in takes me back to the now blank mass mail window, thus losing all of a carefully crafted email. I keep thinking Easy Social would still be active as long as I kept typing intermittently, but it does seem to quit behind the scenes without notification and I keep typing and end up "sending" the disappearing email.

Or has the email been stored somewhere? I didn't see it in "email activity." Would be helpful to know. Otherwise I could try to remember saving it to my cursor...
