Shot in the dark, but have you installed POWERTOYS lately or changed a setting in your browser/security to empty cookies when you close out your browser.
I had to sign in a few weeks ago after I did something like that. But have been fine since.
In IE, you can set satelliteguys to always allow cookies.
Go to TOOLS-INTERNET OPTIONS- PRIVACY
Click on the SITES button. fill in
www.satelliteguys.US and click ALLOW.
See if that helps. If not... Check AUTOCOMPLETE next.
TOOLS-INTERNET OPTIONS-CONTENT
Click on AUTOCOMPLETE
Make sure that the box is checked at least for 'Usernames and Passwords on forms' unless you are on a public computer or don't want anyone else in your house to have IE fill in the blanks for you.
This may or may not help.
Lastly, check the security settings in IE.
TOOLS-INTERNET OPTIONS-ADVANCED
Scroll all the way to the bottom *Security*
and see if the 'Empty Temporary Internet FIles folder when browser is closed' option is checked. Try unchecking it if it is.
Thats all I can think of at present. If it is happening at home
and work, it isn't likely something on your end though.
