Prevent PC to go to sleep when streaming

Is that possible to prevent the PC running Serviio to go to sleep IF it's streaming?
It sounds to me as a "basic" functionality...but I can't find where to activate it?

Thanks for this application which is really well done!

No, known issue with a bit bucket request to resolve. A partial workaround is to use coffee.exe (search this forum for details) or what my kids do, leave a BitTorrent client running as well.

Another good (and VERY simple) tool to prevent PC sleep is Insomnia: http://goo.gl/uyb97
