I've updated my sdk to the latest version (android 4.4) and I started the emulator, but now it seems not possible to rotate the screen with CTRL+F11, the screen change but all the applications don't change. I don't know if it's a related issue but I can see that even if I created a new emulator with menù hw button, now all the applications have the overflow button.
These appear to be bugs in the Android 4.4 emulator. You may wish to track the issues that I filed regarding the orientation change bug and the overflow affordance bug.
Thanks for pointing these out!
