Could you please put this in the MRJApp.properties file?

# COM.APPLE.MACOS.USESCREENMENUBAR
# --------------------------------
# Puts Swing menus in the Mac OS menu bar, if using the Aqua look and feel.

com.apple.macos.useScreenMenuBar=true

This will not only make LimeWire act more like other MacOS apps (when running on MacOS only, of course), but it saves room in the LimeWire window so users can see more stuff. I've had to add this each time I download a new version, but I thought I'd let you know how to also, in case you wanted to add it yourselves. (And save me the trouble of doing it each time you come out with a new release...

Thanks!
A Happy LimeWire User!
