I've heard other complaints about Stockfish 7 (and not earlier versions) and I'm not sure what the issue is.

Mike - I think this issue goes beyond Stockfish 7. I went back to the earlier version that comes packaged with your install and got some bad analysis results. This may be a parsing issue within COW and how it interprets the engine responses. Perhaps a data buffer needs to be cleared ?

I took my original ebook and removed all previously generated pv computer evaluations. I then imported this clean ebook back into COW Windows Build 60. I requested the following engine parms to be set:

uci

setoption name Hash value 1024

setoption name Threads value 2

I asked to use engine: stockfish-18-32-ja

After computer analysis I exported the ebook back into PGN format and cut & pasted the first 25 lines of output... notice the pv scores repeat themselves on numerous lines:

[Event "?"]

[Site "?"]

[Date "????.??.??"]

[Round "?"]

[White "?"]

[Black "?"]

[Result "*"]

I'm going to keep looking at this to see if a work-around can be identified. I'll post again if I come up with something.
