I am running Vista Business 64 on a Dual Core Intel 6.8 with 3 Gb of RAM.
Whilst sitting idly and contemplating the world, my CPU suddenly started in overdrive - about 65%.
On checking the running processes I found that the Ribbons screensaver was the source, running at 56%.
I am NOT using this screensaver, preferring the Windows logo.
Why therefore should Ribbons be consuming so much capacity or indeed, running at all?
