Since I have CC I have a problem with my navigator: the histogram is neatly in the upper right of my screen. However, when I turn to navigator, the picture suddenly is in the middle of the right hand part of the screen and all other information, layers, adjustments etc. change position. This is not workable. I didn't have this problem in CS6. How can I change this?
I don't think too much fundamentally changed between Photoshop CS6 and CC, UI-wise.
It might be helpful if you'd do some screen grabs to show what's happening, because I'm not quite envisioning what you're seeing go wrong.
Keep in mind you can undock panels and move them to where you like, assuming you have the screen space.
