This is kind of weird, but I keep experiencing this problem when trying to look at the logs of a slice in the GENI Portal.
The following screenshots show two different behaviors I observe when I am in a slice page and click on "Logs".
In one case, I see activities of all slice members in that one slice. (This is what I expect would happen.) In the other case, I see all of my own activities in all slices.
(I notice that the URL in the address bar is different in the two cases. I'm not sure exactly what sequence of clicks makes that URL...)
