Rhino can't hold appearance settings

I’m used to my local language appearance since default for my installation package.

But recently rhino tend to change the [Language used for display] settings automatically. And this behavior often cannot be solved with changing to original options.

This occurs severely when I close the file right after openning that file.

Since this could possibly be tied to the localizations, it would probably be helpful to say what the installed language is as well as what it changes to. Also which specific version of Rhino. Perhaps post your system info too.

Thank you. Here are my infomations.
(PS: Is this problem possible from input devices? I’m recently using a 3Dconnexion SpaceMouse Pro Wireless. Problem occurs regarless of it own driver installed or not - Now I’m using this device without driver, rhino can support this without external drivers and works better)
