When a device is already claimed by one application, attempts to claim that device by other applications running from different user accounts, fail.
POS for .NET returns an Argument exception instead of a POS exception. Once a user account receives this failure, subsequent attempts by that user account to claim the device fail, even after the device is released.
This failure does not occur for two applications running from the same user account. Access to the global event is denied only for different accounts.

POS for .NET uses global events for tracking when a service object claims a device. This only applies to service objects that leverage the NamedEvent class. Basic and Base classes leverage this – although service objects based on the Basic class may choose to provide their own implementation.
