Two comments:

1) If you plan on posting CM analysis, you should change the chess notation to
be "Algebraic" instead of the default "Figurine Algebraic". When you copy any
analysis to the clipboard, the CURRENT notation is used. This is why the above
text appears to be garbage -- if viewed with the CM font, it will be Figurine
Algrebraic.

2) On my slower P3-733, CM9000 announces Mate in 13 in 24 seconds. You should
probably go to "Preferences -> Mentor" and change the hash table size for the
mentor engine to 32MB (or higher if you intend to do analysis longer than 5
minutes or so). Smaller hash tables result in slower performance.
