Bug or Something Wrong!!!!

I do not know WHAT is going on, but every time I am typing a text message or anything and try to use an emoticon on the keyboard now... the second I touch the emoticon I want, it exits me out of whatever Im in!!!! Seriously... VERY annoying! Please fix this or I am deleting the app and requesting my dollar back!
