Wordpress version 3.1.2.

The widgets in the WordPress admin dashboard are controlled by jQuery UI specifically the opening and closing is controlled by jQuery UI Collapsable.

When you make adjustment like opening and closing collapsable items the last state is always stored in a cookie and the state should be the same when you come back to the page. The same is true for the collapsable state for the menu items on the left sidebar.

If it is not working for you most likely you dont have javascript enabled on your browser or a plugin is causing a conflict somewhere.
