I was wondering if anyone else has run across this problem.
I had Okey enabled in my NX70, so that when I tapped the battery icon in the status bar, it would bring up the program that I had mapped to the datebook hard button...being Agendus.
Now, in my NX80, I have Okey enabled and the buttons set up the same way. When I tap the battery icon, it will bring up Agendus, but on top of it is the "Battery Information" window. Rather annoying.
