Hello, So yesterday i booted up my simulator and FS2C no problem. 

Today when i did the same thing, When i open FS2C. No good. 

What happens? 

The panels opens for about a second, then disappears. But everything still works. It hears my voice, i can do checklists with the FO, i can even press the mute button on the panel if i know where on the screen it should be visible. 

But i can't see the panel, and i can't open it with pressing the Assigned button for Auto Feather = N. Nor can i open it via the top menu. Because i need to start the pre-flight events. 

 

What i have done/Tried

I googled and tried a lot of stuff.

The last attempt.

I first disabled FS2C. 

Then i Uninstalled NGX 737

Then i installed NGX 737 and updated it. 

Then enabled FS2C and checked the system check. 

Open P3D V4, loaded in the Aircraft. But still same thing. 

It sounds like your 2D Window Transparency Slider in P3D is set to full.

That's why you can't see the FS2Crew panel.

 

Thank you soo much <3. I didn't even remember changing that yesterday. Eben less that that panel actually is 2d. When it looks no nice.
