Vendors of superconforming clothes should include a note in their product descriptions and read-me's, something like this:

"This product will automatically follow the corresponding dials on V4 -- as long as you always use this product fresh, as if for the first time. If you save it back to your library, the superconforming function will probably be broken. Sorry."

Someone explained in another thread about this, that the only way to preserve superconforming is never to save the clothing. He/she said SC is a one-time function; once the clothing is removed from its parent figure the SC capability is lost, so always use the original clothing as provided by the vendor. 

I don't think this is strictly true all the time. I have occasionally had SC function on saved clothing, though certainly not often enough to refute the theory. I have even had it suddenly work after not working in many loads. I tell you, when you don't WANT superconforming, it's a pain in the butt because it forces parameter values and requires you to do an equal negative number just to get the dial to act like it's at zero. When thi happens I usually just delete the parent figure to break the SC bond and reload it. SC usually can't work if the parent figure enters the scene after the SC clothing is already there.
