Output window question

Somehow I turned the ouput window on so it is on everytime I hit ctrl+enter, and not just for errors. It’s showing the size of the graphics and movieclips which i set it to do on purpose, but now it’s getting on my nerves and i can’t remember how to turn it off.
can anyone tell me how to turn it off so it only pops up when there is an error?

Thank you:)
