Issues being logged off when switching between categories

regularly my user name is logged off, after I have logged on with user name and password, when I switch between categories. I log back on only to have it happen repeatedly. This has been going on for a few weeks. Getting old. Anyone have any ideas? Mods?

Click that little "remember me" box right next to the username box and above TOS box when you log in.
That will solve the problem.
