copy and paste only works sporadically with Wacom tablet. All AI versions up to CC 23.0.2
From at least version CS6 to CC 23.0.2 copy/paste when using a Wacom tablet only functions some of the time and I can't figure out a pattern to the behaviour. Using a mouse on the same system had no such problems. This is either using shortcut keys or the Edit menu commands. Problem on Win 7 Pro, although I've heard reports of it occurring on other O/S. This may be a partner to the "sticky rotate centre" issue reported elsewhere and which also occurs on my system.
