I'm on an iMac late '12 running Sierra (10.12.4) using PS CC 2017.1.1 and I'm having a problem I've never seen before with PS. I need to make clipping paths for the images delivered to a client. What happens is when I'm using the Pen tool and while creating the path, the Pick a Filter Type toolbar in the Layers palette randomly turns on and off especially when I am creating a bezier and Option-click on the anchor point to remove the leading handle. I end up having to click twice on the anchor point to remove the handle and I notice the Filter Type toolbar also switches between Kind and Selected. It really is annoying and slows me down.
It seems to have just started with CC '17. I have restarted PS, restarted my Mac, updated CC to latest version, reset Tools, sacrificed a rooster, etc., but nothing has helped. I haven't reset Prefs yet as I have a lot of changes to it and will do that if nothing else helps.
