Thanks for the compiles.
Which is the format (name) of HashFile, the UCI- option Save Hash works with? The ones I tried so far didn't, regards

Hi. Do you need to have a git-hub account to download the files? I can't find any download button. Thank you.

Logging in at github didn't help in cases of not working being not logged in. Seems to be a matter of luck, .bmi2 worked for me two days ago, giving it a try now again, there's no working downlod anymore to be seen for me neither, sorry. Has anybody, who was lucky with download too, already tried the persistent hash- feature?

The problem at the site is the scroll- function of the mouse. Being at right side of the window, mouse- wheel doesn't scroll but enlarge the screen, so one doesn't see the very end of the site that way, only scrolling at left side of window shows all content, thus I was accidentally lucky once the other day but unfortunately not at the next one trial of today, until I finally got the trick now
:)
Anyhow, what's the expected syntax for the HashFile to be saved? Tried don.dat, don.hsh and don.ptt so far, no file gets stored at given path, regards

It is used to save the Hash file for long analysis.

For it to work:
you need 3 options basically:

option name HashFile type string default <empty>
option name Save Hash type button
option name Load Hash type button

HashFile -> set the name of file:
Save Hash -> Save the given file.
Load Hash -> Load the given file.

try the latest DON version then let me know.

Thanks
