When creating new char i cannot choose mithra the mouse cursor jumps off the game screen to the top left just above border of the game. It's also difficult to choose galka, about 80 % of the time it will jump off to same position.

Using mouse to click mithra or arrow buttons to choose produces the same effect.
I tried simplified character creation that did not help, any ideas would be appreciated.

This game isn't mouse friendly.

You'll need to get used to using the number pad or a compatible controller, but you should mainly just be using the arrows keys and enter/escape on the menu screen anyway.

yeah doesn't matter whether I use the mouse or keyboard to select it. I think it might have to do with the resolution as I was using a smaller resolution than my monitor for better fps. I tried a resolution that matched my monitor and had no problems selecting mithra.
