Hi All, I'm using a MacBook Pro OS 10.12 6 with Photoshop cc 2018. When I'm using Layers in Standard Screen Mode the mouse cursor glitches/flickers between arrow and hand and struggles VERY SLOWLY across the pallet. When in the Full Screen Modes it doesn't seem to happen. I need to have several images open in separate windows at the same time to be able to take elements of some images into the others - hence Standard Screen Mode. Very frustrating esp when editing multiple images together with many layers! Any ideas? Many thanks, David
