Hi , I'm hoping someone can help me with this one.

In K3b I want to put the ISRC's onto my audio tracks. When I choose Audio Track Properties for my audio track the ISRC info box only accepts two characters. I need 12 digits for this field eg: CAS9S1900101. How can I modify the program to accept 12 digits or am I missing something obvious here? Thanks for the help in advance!
