Hello!
First of all: My hardware is a 2013 Mac-mini, 8 GB ram + 1TB HD (Intel Graphics -which makes XP11 not usable, and the reason why I bought XP10 few months ago).
Second: I am using a home-made control panel, made up from a keyboard encoder. Everyone of the 102 keys are being used for a different system. I designed and developed it with XP9.7 and it is still working perfectly in XP9, but for sime reason not working the same way in XP10.
The way of setting it up is:
1) Connect the USB to one of the Mac-mini USB ports.
2) Run X-Plane 10
3) Enter Joystick & hardware configuration and then go to key assignments.
4) DELETE ALL KEY ASSIGNMENTS so there are NOT A SINGLE KEY ASSIGNED FOR X-Plane.
5) Go system by sistem as signaled in the panel, and assign every system to a key.
6) Repeat step 5 until every button has been asigned.
This worked perfectly in XP9.
But after doing the very same in XP10, it iw not working well.
NOTE: There are a few systems that have changed in X-Plane 10 so I know I have to figure ot how to reconfigure them, but that's another problem, not a bug. It's a different way of controlling.
My panel is using PAGE DOWN for AUTOPILOT HEADING BUG INCREASE (AP HDG+).
When I push the button for setting the AP HDG it pops up the FILE FLIGHT PLAN WINDOW which should have been overrriden by my key-assignation.
NOTE2: From my point of view, if the system allows you to assign that key to do ANYTHING, it should superceeds the "default" assignment, or (if not) it shouldn't allow you to use it.
NOTE3: The FILE FLIGHT PLAN seems to be hard-coeded into the flight simulator core program, and crashes against a native system feature like USER-KEY-ASSIGNATIONS. Deffineteily there is something weird that shouldn't be working as it is in my simulator.
