IE8 keeps signing me out ever thought i check boxes to keep me signed in

i have vista and recently everytime i shut IE8 it signs me out of everything. i have checked cookies etc and nothing works to keep me signed in. i am really getting tired of signing back in. it happens in yahoo,facebook and anything else that i have signed into it signs me out . PLEASE HELP

Hi aussie2761,
Try disabling "Yahoo Toolbar Helper","SSVHelperClass" Add-Ons from Manage Add-Ons.
If that doesn't help, uninstall IE8 from Installed Updates, disable any third party Anti Virus Prog, re-install it through Windows Update and see whether it helps. Make sure you enable the Anti Virus Prog.HTH.

tried that didnt work but thanks
