Your post is incomplete. It happens to me a lot when I am using the 7sage app on my ipad. Sorry can you type it again. Just select all after you are done typing in case there is some error. This way you won't have to type everything again.
I usually bubble after every question, but I suffered a bubbling error in Oct that cost me 7 points, so I have been practicing doing after every page. Like @"Accounts Playable" said just do not forget to bubble!!!
