In Photoshop CC, the zoom feature is sporadically not working correctly on my computer (MacBook Pro Retina, system OS X 10.9.3). When using either keyboard or menu commands, via touchpad or USB keyboard, the image(s) I'm working with will zoom or shrink but the window jumps elsewhere on my desktop and shrinks with each increment increased or decreased. Then I must manually enlarge the window to see my full image. This will not always occur, but most of the time it does. It "repairs" to correction functionality if quitting and re-starting Photoshop but then at will, starts working incorrectly again until quitting / again re-starting Photoshop. Can you please assist with a possible solution? Thank you.
