I've been running the CPU version 24hrs straight now, and it still says
THIS:
Date of last work unit None Total score 0 Overall rank (if points are combined) 585263 of 585263 Active processors (within 50 days) 0 Active processors (within 7 days) 0
That begs the question: does it need to be running in display mode to work, or will it fold while being shown in the desktop taskbar only?
