I have also noticed this problem. I am running v2.19.982 (64 bit) on Windows 8.1. Defrag runs for a few seconds, then the disc analyser starts, taking more time than the actual 'defrag'. This happened with a drive at 50% fragmented, and at 0% after running Windows Optemise. However, it seems to only apply to the 'full' defrag option. Quick defrags run properly - Ie takes more than a couple of minutes, and actually defrags the drive.
