All credit going to one machine in "View computers"

I have four machines running the new BOINC client (3.20, on Mac OS X 10.3). Looking through the logs, all appear to be running normally, and all have returned results as they've been running for several days now. However, all the credit is being assigned to the first computer in the list when I "View computers"; the rest show zero credit. Is this a reporting problem on the web site, or is there a problem with the machines showing zero credit?

It can take up to a week before credits start showing up. All you can do right now is just continue submitting results. Each result you submit must be verified by two other computers before credits are assigned.
