What is wrong with the yahoo classic mail address contact list book?

My mail address autocomplete stopped working on one account but still works on the second one?

• Mail contact list autocomplete option stopped working on [email protected] but it still works on [email protected]. I had a highly educated computer techie try to fix the problem... First of all, you tell me to double check that Address AutoComplete is enabled. To do this, go to "Mail Options" and in the Personalization category choose "General Preferences." At the bottom of the page is an AutoComplete setting. Make sure that "Use Address AutoComplete (default)" is selected. THERE IS NO OPTION TO CHECK OR UNCHECK THIS!!! Then, you told me to look above the "To:" field while composing an email and see no reference to Address AutoComplete, you are probably using a browser that is not supported. See the supported browser list below. You can still insert contacts from your Address Book by clicking on the "insert" or "To:" link. THIS DOESN'T EXIST ON MY ACCOUNT OR ON ANYONE ELSE'S ACCOUNT WHERE THE AUTO-COMPLETE FEATURE WORKS... It is on your end that this problem is occurring... AGAIN, I HAVE TWO ACCOUNTS... One account does the autocomplete, but the other account, [email protected] does not work. THERE ARE NO, OPTIONS TO CLICK HERE OR THERE... I have done hours of research and many people have this problem, and every one says that it is on YAHOO's end, that they need to fix it themselves.

• Answer:

  Nothing wrong with your computer or account(s)---and there's nothing you can do about it. It's a huge Yahoo "glitch" that has been hitting a lot of (but not all) users. Yahoo has been (?) "TRYING" to fix it for well over 2 weeks, with no success so far.
