I installed IntelliJ IDEA 15 on OSX these days (including studing license) but I seems that I cannot edit any files. When I hit the J or K keys, I can navigate up and down. I'll try to run a Play 2 app, and running is not even a problem. Starts up without any problems...
The read-only mode isnt toggled in IntelliJ and Files are all editable with other editors like VI, Atom
Any hints on this issue?
