Chorus doesn't display Composer

[JoopP]

Hi Simon,

Thank you for MinimServer! I’ve been using Twonky for two years (with Briain’s trees), but MinimServer is much faster. It has some very nice features, especially for classical music.

Everything works fine on my PC and Qnap. There’s only one thing I don’t understand: Chorus doesn’t display the name of the composer when playing music (normally below the Artist field). It’s just blank. When selecting music it’s there (xxx items, xxx albums, Artist, Composer, Composition etc.)
With Twonky that has never been a problem. Other control points don’t show the composer at all (as far as I know, anyway PlugPlayer and Kinsky don’t), so I can’t try anything else. Do you have any idea?
