Hi everyone.My ipad2 has randomly started having what I can only describe as 'siezures' where it goes mad and starts opening and closing random apps by itself. adding letters onto words that have been typed, jumping from page to page on the net and typing itself. It just starts doing this and I have to turn it off.Often the letters will be repetitive such as 'wwaawwaayyaa' it makes no sense I know. It is irratic when it does this.Does anyont have any solutions? I only got it last October and it is not used that much.Thanks in advance
