Lately (as in: this worked before, now it doesn't anymore) my players are unable to see names in the initiative order. That goes for the players' characters as well as for random tokens. It is like this for me as well when I rejoin as a player. While in DM mode, I can see all the names properly. This is true for every one of the 12 people I know playing on Roll20 (mostly using Win7, can't really give detailed descriptions of everyones setup) and across multiple browsers (tried everything from Firefox to Chrome, even IE).
