When I right clicked a picture in Lr (most recent version) and selected "open file in Ps (CC 2014)" Photoshop launched, but the image didn't show up.
I tried several times, with Ps closed or open, but to no avail. Opening the file as a "smart object in Ps" works, and also opening the file in a third party application (Perfect Effects 8) works fine. Just Ps CC 2014 doesn't load the image from Lr.
Mac OS X 10.9.4 and Adobe CC, all products at the most current level.
