If you use access to the "PartsEditorDlg.ActiveDatabaseEx", Mentor LibraryManager reserves Partitions. And you can't unreserve it anymore!!
This simple command reserves the first Partition:
And if you use anything from the Partitions Collection -> all Partitions are irrevocable reserved!
funny but sad example:
And there is no way I can do, to unreserve this Partitions by Automation! - or?
(the Property "MGCLMPartition.Reservation" is just Read-Only )
