I've been using it all the time without problem until last days.
I did not installed any new add-ons or else. I'm using latest version of panel builder for FSX and using the default FSX C172.
Gauges are not sync and some most of them does not respond I have the RPM going crazy, neddle goes from 0 to 35 and back every second.
Once some gauges starts moving slowly then display like speed in knots then stops (like freeze) even if aircraft speed decrease or increase same for most gauges like altitude indicator...
I tried to sisconect and reconnect simconnect but issues are not resolved even if I close everything and restart again all (FSX, sim pluging, simconnect).
