When using the "Move large files to end of drive" Defraggler is going 100% cpu.
The defrag process pretty much halts.
Until Defraggler finds a big file it wants to move it operates OK.
However, the minute it gets to a nice, big ISO file or some such thing, the cpu goes 100% and the defrag process grinds to a hault.
This is on XP SP3 with Defraggler 1.6.0.118
