This seems to be a new issue--Friday night we found that sporadically whenever we either opened our character sheets and tried clicking on macros, or clicked on our tokens to open the window there, everything would freeze. Several times we didn't even have to do that and it would freeze. Sometimes waiting solved it, sometimes we had no choice but to close Roll20 (and our entire browser window) down. It didn't happen every time but enough to be a real inconvenience. This was happening to multiple players in the same Roll20 room, so it wasn't just our computers. Is there a new bug?
