Defraggler 1.10.143 appears to be looping

Hi,

I just downloaded the latest Defraggler version (1.10.143) but the defrag does not appear to end. It seems to get hung up at 40% completion and just sits on the one square although it appears to be reading other files as my directory listings keep changing.

I'm running Vista/sp1 64 bit.

Also, the FAQ said I could click on any square and get some info, but nothing happens when I click.

Any thoughts before I try another vendor?

Thanks,

Dan
