When I play Minecraft, and open other tabs, I result in having tons of stuff opened, so what I do is open the task manager and force-quit them all. However, when I force quit Minecraft (the game, not the launcher) it crashed my computer. It completely freezes and I have to force-shut it down.
Impossible, since Minecraft runs in a sandbox called Java. Thus not a bug and invalid in the sense of this bug tracker.
