Thanks for the reply mate. Yes I've spent ages trying to find out what's wrong, finding links to supposed MS 'fixes' only to find they're no longer available. Even now people are still reporting problems with this update so presumably MS hasn't really fixed it.
As regards a reset, I'm sure I read somewhere that a reset can be done either retaining personal data or not. Is that true? If it is I'd prefer the former option. If I do go down this route I have no idea what to expect so could you give me an idea what'll need to be done or point me somewhere where I can find out
in layman's terms. TVM.
