Thank you for your prompt, and thoughtful Reply, I appreciate it muchly After I posted above, I Reset Safari twice in a row, then attempted to open Twitter. At that time it decided to direct to a Wall Street Journal site? (really?!). So after rebooting yet again, when I tried to open Twitter, it didn't misdirect, but just sat there throbbing. Hmmm... okay.... so just for giggles and grins I went to Google, then from there to Twitter. And it worked?! And has been fine since then?
That said, I have saved this page for down the road because you know... Skynet is gonna launch those missiles one day. That, and I figure that if it hapenned once, it can happen again, so next time your information could be very helpful to me!
