This has been going on for several months since I got my new 2019 Mac Pro. I am running Catalina 10.15.7 now and the latest version of Photoshop CC.
I launch Photoshop - All palettes appear and Photoshop shows as active app in upper left corner. I then click Command-N to open a new document and just get an alert sound, but nothing happens. Once I click on any palette and then click Command-N the new document dialog appears?
If I double click a PSD on the desktop, it opens in Photoshop. Again Photoshop appears as active app in upper left menu. If I then choose any command (such as Command-J, Command-W, etc.) nothing happens but the alert sound. Once I click on the open document window or a palette (no visualy changes occur) all key commands work?
Lots of times I have to click Command-V twice to paste content from another document as well?
It is like the OS does not recognize Photoshop as being the active app until I start working with it and continue to stay working in it?
