Since iOS 7 I have noticed quite some times that, if I have skrittered before, then leave the mobile phone in standby or do something else, that in some occasions when i re-open Skritter and click on start, the character does not appear. I can hear the speech, but the rest of the page doesn't charge. If I try to click somwhere, Skritter moves on the next character (as if I had chosen that I knew that character), but with the next character it happens as well.
Only workaround is to shut down Skritter completely and re-start it.
Does anybody else experience the same?
