Maybe her clamp is gooped up with paraffin waste and the clamp does not
spring shut tightly.  It may also be the brand of cassettes she is
using.  Some of them have a little more give, which can be minimized by
making sure the cassette is filled to the brim with paraffin at
embedding.

i have a friend who says she is getting thick and thin sections because
the 
block can slide laterally in the block holder. using a 2025 my blocks
also move 
but i don't have any trouble with the thick and thin sections. the side
to 
side movement doesn't seem to make sense to me, anyone have any input,
ever seen 
anything like this?
