cannot refresh the system updates screen

[groovydaddy]

Binary package hint: kdebase-workspace

I clicked on Software Updates in System Management, and the program didn't seem to run long enough to check for available updates (maybe a second or two). Then, I hit the Refresh button at the bottom of the window, and I received a pop up box stating that I do not have the appropriate privileges for this action. I haven't changed any settings, so I'm not sure why this would happen.
