[Editor's note: See the comments for a discussion on how to resolve this issue]
I installed an application that came as a .pkg file. By installing the application it altered something in the application folder where the new application was placed. It locked the folder. And now i'm unable to edit in it. I'm not even able to create new folders in it.
Now i'd like to get trash the installed application but it's locked as everything in that folder. I can open everything in the folder but that's about. For some reason the administrator only gets the "read only" privileges. The application was jCalendar by the way.
I hope someone can help me out.
