Maybe you don't have too much experience using Yappari? When I say quit is not closing the application, but actually selecting QUIT in the Yappari menu.

Looks to me that you are closing the windows but not quitting the application so you haven't started the 0.0.29 yet since you're running 0.0.27 and not quitting it.

Why don't you try to uninstall the app, REBOOT the phone and then install it again using the Application Manager? It's way easier than download the .deb file.
