Game vanishes with dual monitors - Cursor won't lock in game.

[Former user]

The problem is, I don't know if it's intentional or not, but the game doesn't run in fullscreen (even in fullscreen mode, i can move my cursor to the next monitor, as if in borderless mode) and whenever i click with my mouse on the 2nd screen, the game just vanish. It's not minimalized, it can't be found on taskbar or in windows tray. But the menu music still plays and if i run the game 2nd time, i cannot log-in. The only way to close the game in that state is through task manager

I've tried to test the issue a little more. It appears that the game does that even without me clicking on the 2nd screen from time to time.
