I think we should try to get deeper into that Scheduler issue now.
Do you have any ideas?
I noticed recently at bugs.mysql.com that they have a pending issue with scheduled backups from 'MySQL Administrator'. Changing the LETTERCASE of one of the parameters did the trick.
Please confirm:
I understand that
1) you add the job to the Windows Scheduler
2) from the Scheduler you can successfully 'execute now'
3) but a scheduled job does nothing – though Scheduler reports that it was run.
Is that correct ?
