???

I have encountered a problem when inputting data in the Composer Track field. Single CDs accept different song writers for each track; however when I inputed song writers in Box sets it isn't allowed. The box set is automatically "unmaked" and when I try to remake the Box Set a message window pops up stating that Composers must be the same. This does not make sense.

Has anybody met with the same problem? Is there a solution.

Regards
