Persistent registry: The registry is a database and is the central storage
place for settings. If this option is selected, then all of the settings made in
the control panel are saved in the registry. Otherwise the settings are lost
the next time the system is started.
If this option is deselected, then it is also possible to save the settings by
running "regsave.exe".
NOTICE
If you delete the registry, the touchscreen calibration will also be deleted;
the unit will need to be recalibrated after a restart.
Adjust settings to match PMI 2xx : If you press this button, then all of
the settings (COM interface etc.) of the predecessor type PMI 2xx are
transferred to PMIvisu/PMIopen.
