i had the same problem try this...
1. five finger swipe in on your track pad
2. click on the mission control icon
3. it will show you mission control in a zoomed out window click it to bring it forward.
4. hit the minus sign bottom left corner near plus sign
5. hit X on the skydrive app to remove it
it worked for me didnt kick me back to the browser when i did it this way. good luck
