fuseesb.log does not get updated after FuseESB has been started

I am testing the FuseESB -37 private beta.

I started a fresh installation on my Windows XP box.

The log in data\log does not get updated since 09:33:xx which was the time the FuseESB was started.
Since I have been running the ESB for about 20 minutes. And recently I have installed the camel-ftp feature.

If I do a log:display in the console I can see log entries about that.

But the fuseesb.log file in the file system is not updated.

See screenshot.
