Since getFontMetrics has been implemented, the error is now

Error dispatching event EventObject { type: "click", class: flash.events::MouseEvent, ptr: 0x11a63e8 } to handler FunctionObject(FunctionObject { ptr: 0x4efaf90, name: "com.corus.speedyMax.screens::Landing/playClick()" }) : TypeError: Error #1009: Cannot access a property or method of a null object reference.

This needs TextLine.getAtomIndexAtCharIndex
