DO12 - Menu fonts, how to change them?

In the save dialogs, menues, etc, there is a font using "antialiasing" or "clear type". How can i set that to also use Arial, as i have it for the other menues?

What's meant by "save dialogs"?

Which menus?

The menues, if i right click a file, in the context menues. Or in the preferences pages. Also, when i use F7, "create folder". When i save stuff, there are dialogs too, using that soft font.

I forgot, in the info tips, too.

Those use the font Windows is configured to use. (Same as most parts of Windows itself.) They can't currently be changed within Opus without changing them system-wide.

Well, if we can change them sometime later, that's fine.
