I'm running a shell command in my 2 perl script. Like I said in the post, the script works fine when I run `/Applications/myapp.app/contents/macos/myapp`. But when I run `open myapp.app` (mimicking someone double-clicking the .app folder) it doesn't work correctly. It loads the first application, and then loads the second app and closes the first app, but it won't re-load the first app (with an error if i run `/Applications/myapp.app/contents/macos/myapp` and no error just wont open if i run `open myapp.app` inside the second perl script). Hope this clears up the confusion.
