Hallelujah!!!
I've been back online now for about 20 minutes going up and down my favorites list and not a single DNS Error message yet!
Thank you all sooooo very much for your help and, especially your advice jdm.
Thank you. Thank you. Thank you. I can't tell you what a pleasure it is to surf uninterrupted again! :)
Happy to help -- you're very welcome. Do keep an eye on it, though. I'll be around later today if something strange happens again.
