I am running the demo version of x-plane, version 10.42 build 104200 64-bit. I am using Windows 10 with a 3.2 GHz CPU and 12 GB RAM. My video card is NVidia GeForce GTX 750 Ti with 2 GB video memory.
The log.txt file is attached from a session in which I opened x-plane in windowed mode, switched to full-screen, and then switched back to windowed before closing the program.
I switched to full-screen by going into the Settings menu > Rendering options, then checking the box for "run full screen at this resolution". The screen resolution is set to "Default Monitor Settings".
The mouse cursor disappears as soon as it goes into full screen mode. If I move the mouse at random and it happens to fall onto a button or control that changes the appearance of the cursor, I can see the changed cursor shape, but as soon as it moves off of that control, it disappears again. I can ctrl-Tab to bring a different program (e.g. windows explorer) to the foreground in front of the x-plane screen, and then the cursor becomes visible. But as soon as I click on the x-plane screen, giving it the focus, the cursor disappears again.
I'm wondering if anyone else running x-plane in Windows 10 can reproduce this issue.
