At the moment the only way to exit(not quit) the game is by using ctrl+alt+del then use task manager to minimise the game which allows you to open a new window if needed. It would be a lot easier if we could use the Windows button which is on most standard keyboards. The problem with ctrl+alt+del is you need to close the task manager before re-entering the game, if you do not close it the next time you press ctrl+alt+del it will not minimise the game.
do you notice this issue on other games?
For me the windows button is working as intended.
Could you try to use alt + tab ?
Most of the other games I run minimise using the windows button, I had forgot about Alt/Tab, thanks for refreshing my mind, it works fine and you have solved my problem. Thanks.
