After working on a file for a bit, all functionality seizes to work after a bit. Can't undo, can't use any short cut basically, but it works again once I go in and out of the window. Is this software issue? Done latest updates (been issue for last few updates). On latest Macbook pro.
Bug, Crash or freeze, Performance, Problem or error
Can you reconfirm which version of Photoshop and OS and how much RAM and spare disk capacity you have? Also, have you tried resetting your Photoshop preferences, which you can do under the General tab in Photoshop preferences?
