Thanks for the response. It's a little disquieting that a problem wasn't actually identified and fixed. I'll clear the cache as you suggested should it happen again- though the spontaneous resolution has me skeptical of that as a solution. I believe I set my browser to clear cache on exit anyway.

Part of my frustration isn't with Cox so much as it is with the fact that everyone I do business with electronically- credit cards, brokerage accounts, banks, utilities- want to railroad me into "going green" and doing away with paper statements, which I need as a reminder to debit by accounts. On a very regular basis popups occur at log-ins where I am required to ONCE AGAIN specify US mail- the defaults are always email only. If I absent mindedly dismiss the dialogs I will have inadvertently opted for "green". I will spare you the political rant about endorsing as factual premises related to political hoaxes.
The point is that this adds to a history of unreliability concerning email... I've had people send me emails that I've not received- and other messages that arrive days or weeks later. It's not frequent but it adds to the sketchy record of something that everyone is insisting I rely on for business communications. Cox has tried this as well... I had to request by phone that they stop regularly and unilaterally enrolling me in "paperless" as I do not see email only as a viable solution when it has been and continues to be less than dependable.
