The thing is that I get the message that LFS can't go to window mode because its not on the primary monitor.

I had the same problem. My own fix was to make the secondary monitor the primary one by moving them around in the windows control panel.

Are you sure about that - sure it was not "ReleasePlateHandle" ? This is the first report of GetPlateHandle failed in X3.

ReleasePlateHandle is ok, not a bug and I'll remove the debug text.
