This is probably a WP 3.5 issue but I thought you should know about it in case it can be resolved in the theme.
On the WP admin panel at the bottom of each page there is "Thank you for creating with WordPress" and then "Version 3.5" over to the right.
On WordPress menus that are longer than one page such as Appearance, Settings etc. this footer only appears when you scroll down.
On the Gallery theme Advanced Options (for example) the WP footer appears immediately and it is impossible to alter the settings that are behind the footer.
