Doesn't Shutdown after Defrag Freespace

When you select Settings > Shutdown after Defrag and then proceed to run Action > Advanced > Defrag Freespace you will find that the software does not shutdown the PC once the Freespace Defrag has completed.

Unless this is by design, I expected the Shutdown after Defrag option to shutdown after any defragging, free space or otherwise.

I am using Version 1.17.172 on XP 32bit SP3.

Many Thanks

Stephen
