Scheduled Tasks Stopped Working

Hello Guys,

I have been using Scheduled Tasks to execute a little batch file for the
past couple of months, without any trouble at all, but after using the
Win98SE set-up to 'refresh' my system this week, I find that my scheduled
task doesn't work, even though the log shows that it ran.

I have just checked and it seems that it works perfectly while I am present
but for some reason it fails to work, when I need it i.e. when I am away
from my desk-top.

Any suggestions?
