Widgets not expanding on wordpress 3.3 widget dashbord

I updated to WordPress 3.3 (manual update) and cleaned browser cache.

Widgets dashbord stop working when tring to expand dynamic sidebars for custom theme when it works for previous wordpress 3.2 installation (using register sidebar on functions.php)

I have tried to install Hotfix 0.8 exension and now it works for twentyten theme but not for my custom theme.

What can I do?
