Randy,
Curious as to what you filled the block with ? I had the same experience years ago with a block I did for a customer that he had filled. He used one brand of filler that I had never used and his block did move around a lot on the first freshen-up and a little bit the second time.

I have always used Hard Block and have never had it move around ?
