I recently purchases a Lenovo P72 laptop. It's running Windows 10 64bit; 16 gigs of DDR, on a i7 8th gen processor. I loaded the latest versions of LR (8.2) and Photoshop (20.0.4).
I encounter a problem when I'm in LR and choose to "EDIT IN" Photoshop.I clean up some stuff with the clone tool, maybe I play a little bit with the Camera Raw Filter, and then I go to save these change and PS and LR both freeze and I get a crash pop up.
When I run them individually I encounter no problems.
