Do not click the Back arrow button on the Browser while using CRM Boost.  Clicking the Back button on the web browser or pressing the Backspace button will send you back to the Log In screen.  Simply click the forward arrow to go back in or log in again if necessary.

All of our modules load dynamically on an asynchronous secure request method thus never leaving the first page that was loaded after logging in.  Therefore clicking the Back button will send you to the previous screen which is the Log In page.
