When you change the zoom settings in Google docs, it changes the context it is sending to the Co:Writer extension. The new context is not reporting the proper cursor location to the Co:Writer extension causing the last letter to be deleted.
Solution: Use the Chrome browsers zoom function when using Google Docs.
