On the "Manage Group" section of the Confluence Administration page, the navigation bar at the bottom always starts showing pages 1-4 as follows:
    [Next] (see attachment)
This happens regardless of how many pages of groups there actually are. This becomes very confusing when there are more than 4 pages of groups. You need to click [Next] when viewing page 4 in order to navigate to the next 4 pages of information. The navigation bar should reflect that there are more pages.
Personally, I think it would make more sense to have the first and last pages always represented in a format similar to this:
[Prev]  . . .      . . .  [Next]
