Hi Brian,

Thanks for running the new pack - you must be ,V! Well spotted, yes I 
upped the version of the cygwin.dll to the latest. During the 
debugging, Markus' got it working and the original hypothesis was that 
the latest version of Cygwin gave us the fix so I upgraded. As you can 
see I've failed to upgrade the "Hevy" pack in line with this - it's 
still at beta 3. I do apologise. I'm going to have to leave this now 
unfortunately for a couple of weeks at least, but may be able to 
upgrade the "Hevy" pack when I get back (there are other fixes to go 
into Beta 4 too).

I do apologise for my intermittency. Thank you for bearing with me! 
It's great that the CGOS ratings are now more stable thanks to Don 
adding the comma suffix merging etc. and guys like you running the 
pack. I wish I could run it more often myself but restrictions on my 
internet connection prevent it a lot of the time. 

Thanks again

NeuroGo is failing immediately for me. I figured out why. I copied 
both Lite
and Hevy packs, and the two have incompatible cygwin1.dll files.

I invoke NeuroGo with "neurogo -config NGconfigB.gtp", and the run-
dialog is "The procedure entry point _feinitialise could not be 
located in
the dynamic link library cygwin1.dll.

Thank you so much for the feedback on the beta 3 CGOS standard engines 
Sorry it has taken me so long to produce beta 4. As usual it can be
downloaded from the CGOS Standard Engine Packs page on the Computer Go 

and Use

Main points:

   * Feedback on Windows 7 showed that the pack didn't work - now
     updated and working on Windows 7. Thanks so much for that!
   * Markus (the author) discovered an old compiler feature/bug was
     causing the instability of Neurogo. This is now fixed. I haven't
     seen Neurogo fail to finish a game since this has been fixed 
     of games played).
   * New engine added, James. This is based on the Brown1.0 source
     code, the idea being that it will eventually replace the Brown
     executable as it can run both the Brown algorithm and the James
     algorithm. Currently on trial.
   * There is a trial .bat file for launching 19x19 engines. Note, 
     feature has had very little testing though.

All the best
