In the past, when I needed to take a screenshot, I would press “8” first, and then press “Pause”, which was able to do something like freezing the screen. However, in recent months, every time I press “Pause”, the pause menu appears, just like when I press “F2”, now how can I take a screenshot without the pause menu appearing?
Press the Pause/Break key. On my keyboard it's next to the Scroll Lock key. Pressing it again restarts the simulation.
