Task Scheduler w/ Access 2002

[TheWkndr]

I have 5 Access2002 programs written with AutoExec queries which I wish to run overnight every night. I used the Task Scheduler, setting up the apps to run as a Local admin. 2 of the 5 run as expected. 3 of the 5 still show as RUNNING when I check it in the morning. I can run them using the run command no problem on the same machine. They take less than five minutes each to run this way, and are scheduled 20 minutes apart. Since it's not really erroring out, there is nothing to be gained from the log.

Any ideas?
