PS: Inverted mouse is ON default in game settings but ingame mouse behavior is same as on the windows desktop. It is not inverted mouse. Change isn't possible...I play with inverted mouse since Quake was released, so for me (And for many other people I hope) is very hard to play with not inverted mouse....

Thank you for the update.
Can you try to remove the contents of your C:\Users\*username*\Documents\DayZ folder, update the game to the stress test version and let us know if you are still experiencing this issue on there as well?
Regards,
Geez

After all steps you adviced issue persist.

Hello Geez,
what about this problem? Can you take a look on this as soon as possible please?
Thank you very much.
Martin.

Hello Kenobi.
We have been testing this issue internally but so far we were unable to reproduce the problem. If you open your C:\Users\*username*\Documents\DayZ folder and right click on the files, then select properties, are the files set as read only by any chance?
Regards,
Geez

Hello Geez.
Negative result, no read only files are there. But in Kenobi_settings.DayZProfile I see "revMouse=0;" which is in conflict against setting that i see in ingame menu. You can see this in video that I added in older comment.
I will do some testing with manually config change and if this will failed, then I will try DayZ reinstall, maybe it helps...
Martin.

I can confirm that if I manually set value revMouse=0; to revMouse=1;, ingame behavior is changed to what I want. Game settings is same as in video I posted earlier, no changes. I don't want to investigate this issue more, problem solved for me so you can close this thread. Thank you for your time, may the force be with you.
Martin.
