I'm thinking the delete will have to be done the "old fashion" way!
When i did this - I went to clean up the mess I had made. I used the Catalog and Categories/Products page under ADMIN... when I chose the X, I was presented with check boxes where it existed - shown as:
Product Master Category:
With check boxes next to each...
So it does seem to know that they are cross Linked...
COOL!
And from the LESSON, i will always sort my file on the "v_products_model" column
