Strange behavior of Safari browser with beta Norton account site

During testing of Norton Security for Mac, I clicked on the Account link in the upper right corner and was transferred to the Safari browser where I was presented an account login page.  I successfully logged into my account, but I could only observe the license information of the beta versions I am testing before the page would be dropped by the browser and I was presented with the account login page again.  This happened consistently three times in a row.
