Hello, Sorry if this problem has been mentioned before, I am new to this forum and did a search but might have missed it. By navigation tabs, I mean the buttons around the 'menu set' center button. You know, the buttons for iso, wb, focus area, and shutter timer. They no longer work to get me to those functions. For example, if I press the iso button, the LCD screen gives me the option to move the focus point around. And the same with the other 3 buttons. Perhaps I changed a setting and forgot? I ran through the manual and menu settings, but could not find any way to fix this. Please help!
