Screenshot in Onenote Troubleshooting Help

[lovenokia]

I have learned how to take a screenshot, than paste the screenshot into onenote, but I have a problem. The first time I double tapped the pen, I was able to take a screenshot and paste it into the open window of onenote(metro) and was prompted to put it into my notebook everytime and I pressed okay. Now everytime I screenshot, it pastes that's screenshot into a new onenote windows. Does anyone know how to fix this problem?
