Wish I had an answer as the exact same thing is happening to me.  In my instance it's logging off and  loggong on every few minutes.  Every so often I will the "...you have been loggged into another machine."  Like you I thought my password may have been stolen somehow so I immediately changed my password, but I still experience the same thing.  I have 2 computers and am experiencing similar results on both.  Haven't tried a new ID yet, and haven't had any luck in finding resources, but am still looking.  I have software/hardware firewalls, virus scanners, and all my wireless protocols are encrypted (not with WEP).  This is a recent issue that just started out of the blue after yahoo officially moved all of us to the new mail system.  Oh, and you gotta love those automated responses from yahoo.  If anyone else has run into this and tried other things to try to resolve it or at least narrow it down the info would be helpful.

Perhaps your login information is incorrect for some of your websites. It might also be a connection issue at your end. Also, have you tried with just one account? Perhaps go through all of the ones you do have for example and isolate the problem that way.

Delete cookies from the PC. and try logging in again. In case you've SAVED previous password, you need to change it too.

If it has been a while since you have logged into that account the Yahoo has probably deleted the account. You may want to try logging in, and then send the old password to your e-mail and see what happens.. If not then I guess that they ID has been deleted and that you will have to get another one.

If you haven't logged onto myspace in a while the password may not be able to be recognized...\n\nYour best bet will be to make a new password.

try opening up ur laptop and take out the button cell that is present on the motherboard. this will reset all the information that had been changed previously and hence ur password will be resetted. :)

you will have to log in again and use your screen name and password. I deleted mine and this solution worked.
