Thanks for that insight. If that’s it, it’s something that can be managed. My main concern is that there’s something wrong with my new system. If this is just a consequence of a laptop gaming system, then so be it I suppose. I’ll just log out/log in of Windows when it becomes a problem.
I’m still thinking/hoping it’s a bug with Windows 10 or MSFS or the combination of those two because if I have a web browser open on the other screen, or sim management programs, or NZXT’s system monitor, but… not the MSFS ATC box, this issue does not occur.
