My visual editor box is huge and while I can make it smaller, it won't stay small. This started occurring a week ago Originally the problem was box shrank way too small but I increased the size and it was temporarily fixed. But I can't keep the visual editor at a manageable size now. I use Chrome and my blog uses the Koi theme.
I know to drag the bottom right hand corner of the box to change the size but it won't stay at the new size. After I save or re-open WordPress, it's back to being huge again. And it's huge on my work computer now too.
