Entering VR Mode in XP12 Disables my Undocked Window

I've incorporated the GNS430 into a Piper Warrior. I have it set up so that one GNS430 window is in the plane's console replacing the GNS 530 that was there, and another undocked GNS430 window is visible on my Air Manager display. It works perfectly in non-VR mode; I can see it and interact with it in the plane, and I can interact with it on my Air Manager display. But when I go into VR mode, it disables the undocked window on the Air Manager monitor -- it edits the .ini file and changes undocked = true to undocked = false. It's still visible in the plane, but when I exit VR, I either have to enable it via the plugin menu and then reposition it, or I have to stop X-Plane, edit the .ini file, and restart X-Plane to get it back in the right spot.

How can I prevent this from happening? I've tried making the .ini file read-only, but it doesn't care and overwrites it anyway.
