While running a recent campaign, I have been using maps from my laptop via HDMI to a large monitor on my table and I project the player screen in spectator mode. What I have been experiencing is that my maps will just periodically shutdown then I need to re-launch the map. I have looked to see if there is any sort of setting that would help that stop that but I have not found anything. Does anyone know how to help prevent the map from just stopping and shutting down?  For reference, my computer is not going into sleep mode and my external tv monitor is not going into sleep either.

i have noticed that after about an hour or so is when the timeout happens. I just refresh the page every now and then. that seems to prevent it.
