SSRS 2008 dbo.ListRunningJobs

I am trying everything to try and get active reports running from 2008 SSRS similar to the jobs drop down while connected to an SSRS instance through SSMS. When I connect via SSRS via SSMS, I normally see a list of jobs (or reports) actively running. I traced my session to see what what was being called and found the procedure dbo.ListRunningJobs. When I run it via a query screen, it returns no rows every time. I have confirmed that jobs are running, but still no rows.Any ideas would be very helpful.Thanks,Bobby Johnson
