Task scheduler: have a task only run briefly?

I've added a task in Task Scheduler that just loads up a

very simple program I have that displays some date

information. I look at it for about 1 minute then close

it.

However, I've noticed that after I close my program the

task is still running. I'm not really sure what it

means that the task is still running, since I've closed

the program the task opened.

In Settings, I've set "Stop the task if it runs longer

than" to 1 hour (the shortest setting), but I really

don't need the task to keep running at all once it's

loaded my program.

It's no big deal and doesn't affect anything, but is

there a way I can get the task to only run for a minute

or so? I know I can manually END the task but is there

an automatic way?

Thanks
