Symptoms
Event object remains in status "checking" forever.
Cause
PATH_FILE_COUNT = 1 used together with FILE_CHANGED, and the interval of FILE_CHANGED is set below 1 Minute.
Resolution
Set the FILE_CHANGED timer equal or above to 00:01:00 and the EVENT object will work as expected. This is function by design. A warning message for users will be implemented in upcoming versions.
