ABSTRACT:
A computer device for logging changes to a user preference includes two log files, and a first and second file. The changes are written to the first file. The changes are then flushed to the log file with a marker. The marker is moved to the other log file before the changes are written to the second file. If the changes are successfully written, the changes are loaded from the second file into short term memory (RAM). If there is a transient error but there are no more changes after the error, the changes flushed to the log file are loaded into RAM. If the transient error occurs and there are further changes, all changes (before and after the error) are flushed to the log file with the marker, after which the marker is moved to the other log file before the changes are written to the second file.
