In the chatbox, when census is running, it says "50 characters processed" when it hits the limit of 50 chars (for example on the largest intervals like 40-45). This is confusing since it looks like it processes those 50 and then do them again when it narrows the interval. Thus making it seem like it counts chars 2, even 3 times. Hope you can tell what I mean

.
Also, there is a bug that makes the social window pop up for each who that census is doing. This is true for all tabs of the social window except for the "who"-tab. I think this was reported in the thread about the FriendsFrame.lua too.
Cheers.
