It would help if you can make a screen recording on your PC while you try to scroll one of the knobs with your mouse and upload it to YouTube or similar. No-one else has reported being unable to use the knobs in this manner that I know of. Thanks.
Yes, thank you again for the request. As you know the developer is well aware of it. Please let’s leave it at that. Repeating yourself will not make it happen sooner.
The secondary database is only available when there is more than one nav database to choose from, i.e. when custom nav data has been installed into X-Plane’s Custom Data directory, for example from Navigraph or Aerosoft.
Can’t tell unfortunately, X-Plane just crashed on its own.
P.S. You should remove XSquawkBox plugin, it doesn’t work on Vatsim anymore, and then you Log.txt won’t be so massive.
Payload whether set by FBO or XP W&B should be saved with state, yes. You can use sensed fuel if you like (by clearing the field), but fuel has to come from the fuel truck no matter what.
