Hi! I think ive found the cause of Naum?s crashes.
Its a learning problem..
Under WB, if you set
LEARN=0
All works fine. Naum plays all the games (match, tournament, etc) without crash.
But the problem continuing as UCI engine (under all the GUI), because you can set "enable learning" as off, but when the games begin, seems that Naum kept the config by default (when enable learning is on).
Under Fritz8 GUI, you can modify the parameters of UCI engines but when you save the news, Naum crashes.
I dont know if Alexander reads this forum, but seems that is a nasty bug, at least for my machine: Duron 800, 128 Mb RAM, Win98SE

I traced the Naum crashes that were occurring in the fritz8 gui to the fact that naum.exe and naum.cfg download as "read only". Use "attrib -r *.*" to remove that attribute. After making the change, naum no longer crashes on my machine.

As Norm already mentioned, problem is most likely caused by the read-only attribute on the naum.exe

It seems that Fritz8 GUI tries to modify the executable which is bad by itself, but then if executable is read-only it freezes which is even worse.

Chessbase fixed the problem in their latest GUI. I have Shredder8 and everything works fine with the read-only engine. When you choose to save parameters, GUI will save them in a separate file (I am not sure how Fritz8 does it).

Hi, Alexander!
Im not agree. Ive tried under Shredder8 gui with the "right" exe?s properties (modified, not read-only), and crashes.
You can test it under Arena....or maybe its only my problem.

I can't repeat the crash you have. Everything works fine on my machine.
Keep in mind that options from naum.cfg are usually ignored in UCI mode, because UCI GUI sends it's own values for those options. This means that you should set-up engine options from the GUI. You don't even need naum.cfg in UCI mode.
If you wish, send me a private message and describe step by step what do you do to cause the crash and I will try to repeat it.

From what you're writing, it doesn't sound like the problem is the .exe file at all, though you'd have to test. You said that BOTH the .exe and the .cfg file are as read-only. The .cfg sounds like a configuration file, and if you're trying to change the configuration (learning on/off and other details) and the GUI is unable to, it may be the source of problems.

Albert,
I agree with your logic but changing only the cfg to read/write and leaving the exe as read/only results in naum crashing on my system. Only with both exe and cfg read/write do the crashes stop. Btw, I am refering to the fritz8 gui and my machine runs xp with an amd 2000+.
