Are you calling localToGlobal before applicationComplete?
Is the app scrolled in the browser?
I solved my point coordinate conversion problems by using object1.parent.localToGlobal(...)
I.e. an object's coordinates are in the parent's coordinate space, so the parent knows how to convert them to global coordinates.
The application is already complete. This occurs after the 4th state transition.
The app is not scrolled.
When you do that, do you specify zero,zero as the point or do you specify the X and Y of the component?
