Why can't I stay logged on to my yahoo?

Cant stay logged in after restart?

• before a few days ago I always checked the stay logged in box on every site I went to.recently I discovered that when I restart or shutdown and come back later I am logged out of EVERYTHING.just as I was making this question I realized I wasn't logged into yahoo.at first I ignored it and decided to wait till it resolved itself but now its kind of annoying to have to go back to the log in screen before commenting or something.I don't know why this is happening but if anyone knows how I can fix it I'd appreciate it.

• Answer:

  if you can't stay logged, it could be that your internet options is set to ZERO to automatically deletes everything after your shut down your PC or after you close the browser. <>to log in always on the log in screen, this cause also when you are using an instant messenger program and logged in on another account. you will be logged off on the website of Yahoo also and has to sign in back. BUT if your messenger is first opened and you had signed in and then you will access another account on the website of yahoo such as on Y/A, then it will be OK. just try to have an attention on which part of your movement and activity of your PC that you will be logged off.
