We see flearn9.dat.

I am a bit confused.

We have a number of PCs running MFoG playing against parts of our 
clusters. On each machine we have checked, the file has the date of the 
original installation. However, the contents of the file is different 
on each machine, and in many places.

When the file gets updated (I understand at the end of each game), is 
there a way that we might inadvertently be avoiding the updates, and if 
not, why isn't the date on the file updated to indicate the last write?

Just to be complete, we run sets of games, and terminate MFoG between 
changes in SlugGo's search parameters or if there is a crash, so I 
expect that the file should be updated regularly ... many times since 
September when we started playing SlugGo against MFoG.

As an experiment we even removed the file from one machine. Runs are 
accumulating but we have nothing significant yet.


Thanks for your time,
