How can I return to menu in Draw Something

After I solve a friend's painting, sometimes I don't want to send him a new drawing. I wish to return to the menu but I can't seem to find how to do that without forcing the app to close.

Solution 1:

There's no option to do so in the current version of the game, you must force-quit the application and restart it.

To force quit on iOS (I'm listing this for others):

1. Press the home button to exit the app
2. Double-press the home button to bring up the open apps bar.
3. Press and hold the Draw Something icon until a red icon appears in it's the corner.
4. Press the red icon to close the app.
5. Press the home button and open the app again.
