This is a bug report against 0.4.3.1.
In net/sf/microlog/util/properties/PropertyFile.java, line 84, MicroLog is checking for \r\n, but if a supplied property file uses UNIX line endings (\n), this will leave the line ignored.
Does some specification require property files to use DOS line endings? Or is this just something that slipped through? I don't think it's a good idea to rely on the developer using Windows (I am not).
