I noted that under my 32 Bit Windows 7, & also my 32 Bit XP Pro, that Defraggler 2.09 goes from a normal map display of the colored blocks, to incorrectly filling the free space blocks in Defraggler with blue or other colors while it defrags the MFT area.
After defragging the MFT, about 5 seconds later when it starts defraggling another area, the map display returns to normal.
