the log folder path is not saved

When I set he filename and path for logging and enable logging,
the logging function writes data into the file in the path, which I
have specified.
However, when I boot my PC the next day, the log file path has changed
to C:\Documents and Settings\user!
How can the log path be saved permanently? Because the “Browse”
button is there, I assume it is intended for setting the path?
Otherwise the program has worked great! Earlier version and this newest
one. [:D]
