There was a small script for autohotkey somewhere in the posts right after release.
With that you can play windowed and activating the script just disables the window frame.
The result is that the games window fills the whole screen and looks like fullscreen but you can Alt-Tab or use a second monitor for something else without restriction and game crashes.
Also this doesn't mess with the game in any way, just with windows, and works with every windowed program, so, it's not 3rd party either and should be no problem.
You could also disable the window frames manually in windows, using the script is just faster and easier.
EDIT: The game should run at the monitors native resolution (1920x1080 for example) for the game to look like fulllscreen.
