Along the way I believe thhe "Master Category" was added to the system. I am not sure how my problem occured, but I have a lot of products with a Master Category of 0. Some are linked cats, others are not.

If its a linked cat I can select the proper cat from the list, but for the ones that arent I don't have an easy way to fix this. Is there a script for updating the master categories. I'm using ZC 1.3.6
