I have noticed that in Planet Press Watch 5.x configuration, if you choose Tools > User Options > Logging > All Events With Details, and then send this configuration and let Watch log some activity, and then choose Tools > User Options > Logging > Start Up and Shut Down Only, that both the ppwyyyymmdd.log file and the Service Console window will record/display hundreds of blank lines. I recall it happening this way in Planet Press Watch 4, as well.
