Scheduler without passwords?

I am the only user of this computer. I do not have passwords (yes, I am
aware of the security risks this involves; my decision).

This morning, I attempted to use task scheduler for the first time on
XP. I got a "you don't have permissions" message; on Googling the error
code (XP's "internal" help was hopeless, even though I have it set to be
allowed to go online), I discover that you can't use Task Scheduler if
you have blank passwords.

Has anyone the solution to this, other than setting a password? I am
aware of - and have downloaded and installed, and it works well (with no
passwords) - System Scheduler from http://www.splinterware.com, but I
find it inconceivable that TS is limited in this way.

(Some of the Microsoft pages mentioned a way of getting round the
limitation, but they seemed to be related to something with a different
name to Task Scheduler.)
