dont know why phpmyadmin keeps bouncing back to sign in page

I have phpmyadmin installed on my server connected to mysql-server5.0: it usually works well but ever more periodically phpmyadmin throws me back to the sign in page for no apparent reason..if I click on a certain table and just that table for a while it will do this:: i put in my username and password, then I appear at 'that' last table I was trying to connect to...:: have no idea how to fix this.:
