Task Scheduler bug in Weekly schedules

Archived from groups: microsoft.public.windowsxp.general (More info?)

I have scheduled a task to run every 2 weeks daily at 1am except Monday.
During the first week the Sunday run does not happen but gets scheduled for
two weeks time as below:
System Date Next Run
Mon 1 Aug Tue 2 Aug
Tue 2 Aug Wed 3 Aug
Wed 3 Aug Thu 4 Aug
Thu 4 Aug Fri 5 Aug
Fri 5 Aug Sat 6 Aug
Sat 6 Aug Sun 14 Aug

It seems that Task Scheduler always begins its week on Sunday, although the
list of days and the calendar both start on Monday.

(The reason for the peculiar schedule is that each Monday I will schedule a
full backup and then on the other days an incremental backup. There will be
two cycles running going to two different backup files, hence the scheduling
every two weeks.)

I'm not looking for workarounds (I know I can schedule my full backup for
Sunday to get around this or drop the incremental backup on Sunday), just
asking whether I have missed something?

Thanks
