We are running MagicInfo Pro 2506 on a XP Pro SP2 box, scheduling a standard presentation to 4 screens with 2506 also. The template just runs from 9am to 6pm Mon-Fri, repeated weekly, for a year.
However, the schedule drops out every week, so if it plays on Monday, it won't the following Monday, even though the scheduler shows the job booked throughout the year.
