I started out by creating a new Cocoa application project in Xcode. Then I proceeded to open the "MainMenu.nib" file in Interface Builder. After making and saving my changes, I did a build in Xcode. At this point everything has worked flawlessly. Now when I go into my project folder, I open and test the program. Everything works. Then I take the built application and move it to another location on my hard drive (it still works). But once I move or rename the main Xcode project folder, my application stops working. All I want to do is make an application that can run independently. Because it seems like it needs files in original directory (even after I compile). I sure I'm doing something really stupid, so if you could help me out, I'd appreciate it.
