Session Timeout

I have the session timeout set for 90 minutes. Some of our users go
to compose an email and in less than 10 minutes, sometimes only 1
minute into the compose, it times them out and logs them off, without
saving any part of their message. We're using version 0.1-beta2, the
latest stable one. Does anyone know how to fix this? I'm going to
search the tickets for a solution, but thought I'd post in here to
help get this solved as it is quite frustrating for some of our users.
