Hi Keiron, while we are at it, here is another one :
- Select any (short) list of your Observing Lists and Highlight Objects.
- Forget this list and select a star on the sky chart.
- Now in the list menu found at the bottom of the chart, click on Select Next Object
- SS6 Pro complains and say that this star doesn't belong to the highlighted list
- Click OK and try to do anything with the list menu found at the bottom of the chart !
Here you are !!!
