I downloaded the program yesterday and it worked wonderfully

The built in XP defragger kept stopping after about 4% when trying to defrag my C partion.
Another defrag program that I downloaded, completed but left huge amounts of the disk fragmented.
I have google desktop (I turned that and Kaspersky off) and your program left all my partitions looking wonderful.
The question,
I have set up JKdefrag to run once a day but would like it to use the "a 3" option.
How do I do that?
I know how to do it from start/run but not when using 'scheduled tasks'.
thanks again,
Michael
