Sorry for the quintuple post or whatever, but just thought I’d mention that it’s fixed!!
I launched PS and then began googling NVidia photoshop cursor stuff. Then Photoshop was done launching and opened. I switched to PS to confirm the problem, and… IT’S MYSTERIOUSLY FIXED.
It wasn’t working last night, and I didn’t do anything regarding PS. Just worked with a client in Final Cut Pro. But now it’s better.
I noticed that the cursor was set to the “standard” cursor (the brush when painting). I’ve always used the circle cursor when painting, so maybe my cursor prefs were deleted overnight.
Anyways, I’m happy. Thanks!
