Hi @N953RC9903,
actually it seems to exist a limitation in some cases with touch screen simulating direct mouse-clicks on pop-out instruments. There are already some threads in the forum, for instance here.
If using instruments in Airmanager the touch or mous events are injected to the sim by directly changing values and not sending mouse-click events.
But I do not know if this is only related to GT750 or also stock MSFS touch instruments?
