..whenever I open 'chrome' as my home page there appears a cream coloured banner about 1cm wide saying 'Chrome didn't shut down correctly' and a Restore button. Can someone help me to correct this, please.
Chrome is Not the best of Browsers and, whilst I am Not a Fan of Internet Explorer, I would choose IE in preference to Google Chrome. I think the best Browser is Firefox.
Make sure that your Chrome is up-to-date because the message you are getting has been known to present itself when an up-date is required.
