Standby and Backup Oddity

After doing a full system backup with HDClone from within Windows XP sp3 I
noticed something odd.

I keep this desktop on a short leash for power going into standby after 20
minutes and rarely turning it OFF. After the backup completed I disconnected the
external HDD and walked away. I was doing other things in the area and, after 20
minutes, I noticed the "Saving Your Settings" message Windows displays as it
goes into standby. However, a second or two after it went into standby it woke
up! I let it go through this cycle a few times and figured the backup software
had disabled the standby feature to complete the backup.

I rebooted the system and waited - still awoke from standby on its own!

I shut down the system and waited a minute and it *still* awoke from standby on
its own!!

Finally I shut down the system, pulled the plug from the wall, waited a minute
and restarted. FINALLY the auto restart from standby disappeared.

Anyone have ANY idea how this can happen. I have done this every month or two
for a year or so and never seen this before. Since the backup software is run
from within a running Windows XP system I assume it is running some kind of
virtual machine but I still find it surprising that some code would require the
removal of power to stop it.

Any Ideas or WAGs?

John
