My classes are just class definitions.
MYAPP.Class1= Class.create({...});
MYAPP.Class2= Class.create({...});
I don't create the objects until I get to main.js, which creates them
after the window has loaded. Why is IE7 not giving an error when I
access MYAPP in Class1.js and Class2.js, but is giving an error when I
access it in main.js? This native and function object talk just went
straight over my head. I am only a beginner to JS.
