Log file System
In the
AT4039EML
BERT there is a log file system, where every exception handled or
unhandled by the GUI will be saved. After the first run, the GUI creates a file in the main
directory/exception log, and saves all the existed exceptions. In case the user had a
problem with software, he can send the exception file to our team.
