title: .app made using PyInstaller closes straight away?
body: <p>I have attempted to convert my python program into a .app using PyInstaller. The actual code runs fine through IDLE, but everytime I try and run the newly converted .app, it closes straight away. Below is my .spec file and my .py file. I have edited the .spec file, adding in the text file I import in my .py file.</p>
