Ok well the issue is, is that I can't actually enter the Terminal window to edit it out . . . and I can't find that ~/.atom/config.cson file in any case. Perhaps something broke when I Force Quit the app??
Nope still no window showing. Been looking around and wondering if the 'complete path' on terminal should be different . . . ? Seen as Atom worked with the 'Stack' rather than 'Cabal' previously . . .
