When you are done for the day, do the usual fix -- clear ALL your temp files and cookies, and shut the computer down. When you start up tomorrow, open a fresh browser and log in from the regular log in box on the home page and let me know if that makes a difference.
If you haven't cleared your cookies the machine may show you as already logged in and you will be on the News/announcements page. That may be OK, see if you can get around from there.
I am not sure what is causing this problem, we will track it down.
