Problem with Celestia via Remote Desktop Session

[Dok1eo Sarangaengmu]

Celestia works fine with real Monitors, but fails with RDP-Sessions and generating this message:

Error: LoadLibrary with error 87: The parameter is incorrect.


Workaround for me is to disable within RDP-Session the real Graphic-device.

Prg: Celestia, currently 1.6.2.1
OS: Windows 10, currently (2004)
GrapicDevices: Virtual Desktop Display and a real AMD RADEON HD 6450
Displays: Remote Desktop Session App's/Prg's, and 2 real Monitors


In fact: The user is always forced to disable any real Grapic-Device, within RDP. That is not the normal method!.
Can you fix it, in the next/further Versions?
