Something is very strange with Shredder9 and the Fritz UIC. I have reported on
numerous crashes with other features such as attempting to use some of the keys
in the databases such as endgame and strategy keys. Others haven't found this
and now you report that the saved analysis feature on move takeback doesn't seem
to work. Chessbase support seems to have disappeared these days. However,
overall I like Shredder's evaluation of positions and the other features that do
work and thus do not want my money back. Don't worry too much about the move
analysis feature not working. It saves a little time on analysis in takeback
situations but it must cost some on Shredder's overall strength when not taking
back moves because it takes up valuable hash table space. However  a forced
moveline is where this feature really would be a net benefit to the engine.
