As an active Photoshop user, I usually get this error message a few times a day:
Well today I decided to do something about it, dammit. Turns out it’s an easy fix; just go into the “General” tab of your preferences and uncheck the box called “Export Clipboard.” Duh.
As image file sizes get larger and larger, I don’t know why Adobe doesn’t disable this by default in future versions of Photoshop. Do many people actually copy something in Photoshop and want to paste it elsewhere?
