Choose between dark and light mode

I'm not even sure if this is intentional, but Nitro Studio 2 Deluxe appears to be in a "dark mode" of sorts. The original NS2 is white.

This conflicts with the Bank Generator, for instance, where the text is white but the context menu for selecting a SWAR is also white, so text can't really be seen.

So I ask for a possible way to revert to the white background like the original NS2 does.
