I have an odd issue with VIEW RAW when mapped to a User Key. I've tried mapping to user keys 1 and 2, with the same effect.
The issue being that the view gets stuck in RAW mode, and pressing the User key does not toggle RAW view. Weirdly enough the button works like it should after I've mapped the function to the key, but stops working once the camera is shut down. In other words, the toggle no longer works after a re-boot.
I can force it to work by entering the menu and mapping the function to another User Key. But again, the button only works until the camera is shut down.
I'm now on 30.6.12 and the issue is still present. I first noticed the problem in the firmware which fixed the noisy blue channel (can't remember the version number, though).
