Weird problem, let me explain.
Also I see Pete is out until mid October so I hope someone else has some ideas.
First, new Windows 10 64 bit PC, new FSX (box) install, FSX works ok.
Normal behavior: start FSX, load C172, any field, active runway.
I use the windowed mode and as soon as the scenery finishes loading and I see the aircraft on the runway, FSX is completely active. Meaning I can move my joy stick, throttles, switches, move the window around,see the prop spinning, etc..
Now, if I load a registered copy of FSUIPC (tried v 4.946 and the latest 4.957) and then start FSX with the same aircraft, field, etc here is what happens.
Scenery finishes loading, you see the aircraft but everything is frozen, props are not visible but you can hear the engine running. You cannot move the window nor activate any controls, no action at all for about 1 minute.
After 1 minute or so, everything resumes normal operation, prop spins, controls work, etc.
It is as if FSUIPC is looking for something, loading something ...
I have nothing set in FSUIPC, just stock as it comes after an install. Weird.
I can reproduce this every time with the only variable being whether or not the fsuipc dll is in the modules folder.
Any ideas?
Thanks
John
