Another navigation related one: when you once opened the shutdown menu (close MP, restart MP, Standby, etc.) and exit it again by pressing ESC, you are stuck in the shutdown bar and cannot exit it by clicking up.

Can not reproduce, pressing esc in shutdown menu always exits the menu. Tried it with classic, basic, extended home screens. Might be related to your custom colour theme. Or this may of been fixed if you are not using 1.4 Pre-release version.
