This reminded me to try the CJ4 out, so I checked the changelog prior to download, and found this under known issues:
The joystick used for panning charts does not work in Legacy interaction mode
They recommend using the lock interaction mode.
Please note that the core sim interaction/model behaviors have changed dramatically with SU5, and there is a new interaction system. See the Known Issues for some issues with this. We highly recommend using the new LOCK Cockpit Interaction System with Instrument Tooltips off. To access these settings, go to Options → General Options → Accessibility.
