If I knew how to wok the replay button it would have included a Tomcat. Can anyone tell me how to use it please?
Sorry for a rather overdue reply but I think I can help here.
What you need is a free add-on piece of software called FSrecorder. Basically what it does is record a flight as data such as speed, location, heading, altitude, etc and then can play back that flight
as traffic if instructed to. This means that you can fly another flight at the same time as your original flight is being replayed as traffic. This can be repeated several times to build up a multi-plane screenshot but it requires some patience.
FSrecorder can be downloaded
here - it's the first download on the downloads page. Simple!
