Hi blackbird71: Thank you for your reply. The pages are not the same. I have tried various pages and all open with Chrome no problem. Amazon.com is an example of one page that will not open with Opera. I am not using a proxy nor any type of VPN, just straight through to the Internet. One thing I have noticed is that any pages that have successfully opened in Opera will open again if I close Opera and reopen it; however, new pages typically won't open.
