We'll almost definitely have the use of the Mac menu bar in there for all Mac versions for the next release. You also may see an option for "useScreenMenuBar," something like that, in your "limewire.lax" file. You should be able to set this to "true" to get the menu to appear at the top of the screen.

As far as the result sorting, this is sometimes tricky because it requires a fairly quick click -- it won't sort on, say, a mouse release. Are you sure that it will never sort with a click? I can look into this further on OSX as well.

Thanks very much!
