You are using a character on your keyboard that the login does not recognize or does not allow. Do not use dashes or any symbols that might be causing this.

Get a new account, is my best suggestion. Next time make sure you close your session before leaving the computer.

do you have a lot of programs loading at start up because the can slow your computer way down. Just make it so they don't start up when you first logon.

◙ i'm logged in there and it's working fine. turn your computer off and back on again that fixes a lot of problems.

i think u need to log in as an administrator . do it like this :\ncontrol panel > user accounts > change the way users log on or off > UNcheck the two options .\nthen log off and log in again , now you have to write the username and password by yourself .\n\nUsername : administrator\nPassword : "blank"     >> ((if u haven't change it))\n\nnow you are the administrator and can do whatever you want . \nGood Luck

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.

when you double click the browser, it will ask you if you want it to be the default browser. If not...go to control panel,Add or remove programs, and select Set Programs Access or defaults\nI don't think the browser it's auto filling user name & passwords, it allways ask's you if you want your account auto filled.If not...click properties on your browser and uncheck the box where it says about auto filling username&passwords...it has to be somewhere in properties. Good luck dude and don't swear me if im wrong :D

Try to restart your browser or your whole computer, also check your email for an activation email and it will automatically log you in  as you activate it through a link. Or write to yahoo's techinal department

Check your internet security settings. They may be set to not allow cookies. Many websites require cookies to log in. The other thing it might be is a spyware/adware program. Download and run Ad-aware. Finally, it might be a program designed to auto-fill pages. If you know of one of these running on your machine, try to remove it.  Good luck!
