PS constantly freezes, moves slooooow, and then it crashes. And this is even sometimes before I have a chance to open an image. It usually crashes during camera raw, lately. I have tried to reset the prefs multiple times. It was running just fine before the update. I check task mananger, and my memory usage is at 97-98% without even yet opening an image, and photoshop is using pretty much all available memory. I am running windows 10 on a PC. 16 gigs of ram. Thanks.
