When installing 12 I chose the "import work environments" default option,
along with all the other "default" option.
Under options>work environments my AC 11 "Scheme options" are there, but no go, even after highlighting scheme, choosing "Apply" and "Ok" (several tries).
I noticed in the install notes; that "new" options in 12 would not be there, but it said nothing about none of the options working.
Have restarted AC 12 still no go.
All other things so far look normal.
