Valid from List & Label 8
If you run List & Label within a Windows service or as .NET win service a windows system user account is usually used. As you can not interact with the program List & Label automatically suppresses any message-boxes. Instead of halting the thread List & Label selects the default button. If debug mode is enabled the message is additionally logged in the log file.Please note that you need to purchase separate server licenses in order to run List & Label within a service. We suggest to use the Enterprise Edition starting with version 13.
