I regularly notice that if I open in a file in Explorer that launches an app that's not opened, or launch a taskbar app, it will open on the opposite monitor.
It's baffling since I often physically move my main monitor, either bring it closer in front to sit back and play a game or rotate it to the side so I can watch videos from the nearby couch (with a trackball as controller).
I never determined that it was opening them in a remembered fashion, in fact I'm pretty sure that sometimes closing the window from my main and relaunching another file it will pop up on the other side again, so I made a habit of dragging files to prevent that.
The impression I got is that it is spreading to the less busy monitor as a "favor", but it's not consistent - can't reproduce right now. I really have no clue what the logic is, and whether it's the behavior of some apps I use or the OS, or something weird related to having 2 mouses plugged in.

Either way, it's very annoying.
