Welcome to the forums!
If you want to stop and start a chart, or check the status of a chart, please look at page 143 of the PAC Display users guide.
(It is also installed on your hard drive).
If you want to save the strategy, that is a little more difficult as you have to stop the strategy from running before you can save it.
Also, you can save the strategy to the controller when you download it, and that is the better option.
Why are you wanting to save the strategy from PAC Display?
Can you tell us what problem or feature you are doing?
