Unit Error Fix
Adobe Illustrator CC refuses to remember General Unit setting on Restarting the program it switches back to Points, even tho i set it to mm under Preferences - Units - General. This was never the case in any itterations of illustrator & should be categorized as an error fix rather than an improvement, i would like to see this changes asap as its rather disruptive
Did you try changing your prefs with no documents open? That changes the program prefs not an active document pref.
