When we were playing tonight, one of my players suddenly lost the ability to ping. It had been working previously without any issues. Also, when they tried to use the drawing tool instead, no one else could see their drawings. Ping and drawings worked just fine for everyone else and the player with the issues could see everyone else's pings without any problems. I don't have all their specs (I can ask about it if needed), but we were running through google hangouts and they usually use firefox in windows 7. They were able to see the maps just fine and had no other issues. It slowed the game down a bit, but we were able to work around it in the short term.
