FCKeditor.Java: connector.userActionImpl required to be set?

Hi, I have a small question about behavior I've observed in FCKeditor.Java 2.4 beta. I'm not sure whether this is a bug or if it's an instance of "I'm doin it wrong" so I figured I'd ask here first.

Initially upon setting up FCKeditor 2.6 with FCKeditor.Java 2.4 beta, with no fckeditor.properties file supplied, if I go to insert an image, then click on Browse Server, the browser popup appears, instantly followed by an alert saying "The current user isn't authorized for file browsing!"

However, if I supply a fckeditor.properties file under my app's WEB-INF/classes folder with the following line:

connector.userActionImpl=net.fckeditor.requestcycle.impl.UserActionImpl

The Browser then works and lets me upload files, etc.

I was wondering whether this is fully desired, or if FCKeditor.Java should perhaps be falling back to a default implementation if none is specified in the properties. Or perhaps there's something completely different that I've failed to consider.

Any suggestions?

FWIW, my server environment is Tomcat 5.5 on Windows XP Pro SP2.

TIA.
