Hey Russ,
I was having the same problems, I dont even try to contact them, waste of time
Yahoooo is migrating to a new email, they ask me to move or keep as is, being an ole guy no change
What I learned, I used internet exploder and now days from what I understand, IE is not worth using any longer.
I have downloaded Fire Fox, now no problems with Yahoo.
I would suggest downloading FF by it's self, not through Yahoo, if you do your married to Yahoo
Download FF stand alone, your not married to anyone, Yahooooo, crume, or ?
Check it out, maybe you already use FF
Still have my yahoooo mail (should go see if my Excite account is still out there)
