Subtle changes, bugs and feedback

keep getting logged out - sometimes as soon as i've logged in, sometimes whilst trying to submit a post? two different machines, both firefox on vista/xp

This has been in the last hour?

Could you let me know the following:
1) Are you using SSL?
2) Did you click the "Remember me" box when you log in?
3) What action were you doing when you got logged out (such as, attempting to go from http to https)
