Is it just the system I am using (cable modem), as I need to use the refresh button to update postings? I need to do this even when I go to different web sites and come back. Am I supposed to be "logging out" each time I depart?

 

I get a "Page Expired" warning after posting a message! Although I just hit the "Back" button to return to the particular message board I am viewing, it can get annoying. What gives?
