Thanks for your quick response.

If you want, I can run various tests on Korean Letter for quick search.
Please contact me if you need my help.

oMega Commander is the best!

Meanwhile, which soft-keyboard do you use? Is it Microsoft IME or Microsoft Old Hangul?

I'm using Microsoft IME on Windows 10.

As you can see in the picture below, Korean Letter is not working in Quick Search.
If this is a bug, Please fix it.

Thanks.
