After upgrading from GanttProject 2.8.10 to 2.9.11, my system doesn’t recognize the file dependency of the .gan files to the application any more – in my case it is taken to be a BBEdit document (see »FinderInfoForA-gan-file.png«).
I even couldn’t redefine it in Finder, because GanttProject.app is not correctly recognized as an application (see »FinderRedefiningFails.png«).
Any suggestions on how to fix that?
GanttProject 2.8.11, build 2393
Mac OS X 10.12.6
