Adobe Photoshop CC Version 2015.0.0 is repeatedly crashing, where the previous version did not or very, very rarely crashed. OS is Windows 7 Pro, 64 bit, Intel Core i7-3770, with 32 GB memory. More often, but NOT always, Lightroom and PS are both open. I've closed all other programs - opened Bridge and cleared the cashe.Restarted machine several times, with only PS open and problem continues. This should not be happening.
