mac language(korean) cmooand key problem

Hi.

I'm using an iPad that connects my MacBook.

When I use English, It works perfect.

But when I use Korean (changed language by "left caps lock") cmd key doesn't work.

I can't use copy and paste (cmd+c or cmd+v).

When I press cmd+c or cmd+v in korean languae. I can see "spotlight" on my screen.

But it's good on parallels Windows. (changing language by "right opotion")

If I change to korean by flag icon at the top. It doesn't work either.

I love this app. please help me.
