I think you have to wait for the update package that will be released soon. I think that will fix the shoutbox time out issue, there have been 2 diffrent issues with the shoutbox timeout, one is a DB issue where you need to remove one parentese from the shout block code in TPortalBlocks.template.php
Another seem to be just an issue with themes (Amber and Helios) for some strange reason, but we hope that the updated themes that will start to role in for 1,1.rc3 and Tp V.095 to morrow some time.
Be patient and hope it will solve the issues you have
