Child products

[Matt_Ginn]

I have a product with a custom field (stockable variant plug-in) for colour and size. Due to the large number of options, I end up with 144 child products. All the child products have created OK. However, when I go into the parent product and try to set the custom field values for each child, it won't allow me to save! I have another product that uses the same custom field but only has 92 children and this works fine. Is there a maximum number of child products?
