Hi everybody. My first post. Really appreciate whatever assistance people can provide. I referee a game once a week. Roll20 works absolutely perfectly (more or less) for the players but for me, after about an hour of using it without fail everything on my PC begins to slow down chronically to the point that I end up having to turn off the laptop and re-start. It then seems to work OK for the remainder of the evening. Any ideas what causes this? What can I do to stop it happening? Thank you Martin
