Make PON work in background

[Patin]

Hi, I am playing with a Steam version of PON (I also have a gamersgate one, but did not want to get into the upgrading mess) which I have set as windowed mode and I have managed to play as such. But the thing is it does not seem to work unless you have PON selected. So if I am for example browsing, the turn does not advance and in the end the windowed mode seems to be useless for my case.
So, is there a way to make it work on background? Am I doing something wrong?

Thanks.

Forget about this, just saw the option in the game settings.

Cheers.

The game defaults to not run in the background, to reduce electricity usage (and laptop life)
