How do i make TeamViewer NOT lock the host computer after session?

I have been using TeamViewer 9 to remotely control a computer i'm using to host a dedicated Minecraft server. Everything works great, except, after i'm done remote controlling it, the server computer goes to the windows XP lockscreen. That is annoying, because it makes the server lag. Is there any way i can make it not lock after i disconnect? Thanks! While in session at the top toolbar there's an "actions". Go to lock computer screen and uncheck lock on session end
