First of all, I cannot speak English well.

I found a bug. I'm using Korean&English.
When I typing something, there is underline under the text and I will call it 'edit mode'.
In this edit mode(remains underline) when I move cursor to other place, there is still underline and when I type something in other place, text is entered next of undetlined text not cursor is on. I think edit mode should be clear when cursor is moved.
I feel it's critical bug and I hope it would fixed ASAP. Thank you.
