I've had an ongoing problem when clicking on a menu in Adobe Photoshop CC on a Mac Pro.
Periodically, I will see the following behavior:
When I click on a menu title, the cursor blinks after a second or two delay. Before the cursor arrow blinks, if I try to slide down to the menu items, the menu deselects and does not allow me to choose a menu item. If i wait for the cursor blink after a second or two, I can slide down to the menu choices and select it as usual.
I am stumped what is causng this. I would love help from anyone who has an idea why this happening.
It really slows down my workflow because I can't select menu items quickly and efficiently.
Thank you in advance for your help!
