I've got a simple test app with a custom view (set up in Interface Builder) with its origin at (20, 20).

I'm using pixie to make sure I'm clicking right at the lower left corner. (If I...
I am sure it's something easy, and I am not looking to the right documentation. I need to get information about the application that handles the active window.
