Problem with arrow wheel on my GH2

[Itamar]

I don't know wether this started after installing the new firmware, but since about all the buttons on my GH2 only function as focus area aids. No ISO function, no White balance no function buttons; only focus area aid. It's crazy. In the setup menu everything seems OK, but it just doesn't have these functions anymore when I want to use it. I don't understand what's wrong.
