More thanks for the replies; I've managed some form of reset, but fear I've made things worse!
The keyboard is now extremely erratic, and often hasn't even got numbers, this makes things extremely difficult. However the worst thing is that the wifi connect can't be accessed, as when it requests the security key it will only take the first three letters/numbers.
The date on restart was current, so does that rule out the battery?
Once again thanks for the help, and hints.
