Game should pause while dialogs are open

[mechanical-snail]

If you press the "Release Version" or "Save" buttons while the game is running, it keeps running while the dialog is open. It is therefore not clear what version is being released and what state is being saved. The game should pause whenever dialogs are open.

(Version 1.1.1 on Linux)
