session info updated only after refresh causing theme to load last page theme
placing a debug code print_r($_SESSION['s']['theme']) into ./lib/classes/tpl.inc.php displays the problem.
"default" is the theme on the login page but when a user logs in, the debug info still shows that 'default' is still the theme causing partial css issues when the users theme is not 'default'. Some css is mixed 'default' and whatever the users theme is. Hitting refresh fixes this as it appears to update the session information with the correct theme.
