I figured out my issue.  I had set 'Default login cookies length(in minutes)' to 0 so that users would remain logged in forever.  This caused the issue I posted above.  By changing this value to anything besides 0 it resolved the problem.

I have searched the forum but no clear answer emerged. It would be helpful if you could put a sticky subject out there that addressed this since a lot of people seem to be having issues with it and no clear instructions seem to exist. Would help a lot of us who have defected to Simpleboard but would use SMF if the integration was complete.
