I don't know if this affect other users, but most of times when the Scene Parsing and Geometry is running and you press Stop - it doesn't STOP.
Is the most annoying thing in Corona, that when you press the Cancel button or Stop button, it doesn't stop the render. It has to go until the end of the calculation to stop. So, must of the times we have to wait like 15 minutes or 20 minutes until we can start work. Is this a bug?
