Well, as I've been at this only a couple of months, I can give a newbie perspective. I have this problem too, however I'm noticing now that it's getting significantly better as my fingers get more calloused and used to it. My supposition is that the pads are getting harder and smoother, and the string isn't "sticking" on the finger as much now. I'm also noticing the the temporary grooves in the pads right when I stop aren't as deep, so that would seem to support this theory....
