but it is their fault they releasing bug-ridden drivers without bothering to test them at all. I don't necessarily blame Wacom for having difficulty squashing bugs. I'll try this new 6.3.19-6 release, but I have little expectations that it will actually be bug-free - more a matter of if I can live with the bugs it (probably) has. I'm still using Driver 6.3.15-3 because thus far, it's the last release WITHOUT major bugs. I suppose OSX may have made the difference, when they started REQUIRING reboots upon driver update (didn't need that before).

Horrible development and unlike Wacom in the 90s or 2000s.

Eventually landing on a driver that seems fairly stable. make 4 more versions, all introducing NEW bugs over the next few months. When you launch Illustrator with Wacom tablet ON, youll be shown a message asking if you want to let Illustrator control the TabletDriver. It can happen when Illustrators control over TabletDriver is disabled in the macOS privacy settings. This seems like standard practice for the folks at Wacom now. This issue occurs only when you use the latest Wacom driver 6.3.37-2 with macOS 10.15 (Catalina).

It removed ALL functionality of modifier keys (Command, Option, Control) in all apps which weren't 'Wacom-aware'. WacomTablet_6.3.19-6.dmg was release on Dec 23rd.
