I would like to know why I am getting double group notices for every group that I belong to. Any help appreciate I am on a wired connection. This is not just happening for aone or two grous, it is happening for all groups. It also happens in the SL V2 viewer as well a Firestorm. Also I ran a speed test on my connection, I am getting 21.87 mbps down and 6.65 up. So speed is not the issue.
