Everyone already tried clearing browser's cache to see if that helps?
log out and then log back in fresh?
I have my Firefox browser & Flock browser set to clear cache & most cookies when I close them.
I don't use Microsoft IE very often, but here is some info on the settings for it -
[TipTip: You can adjust your Internet Explorer 6 settings to automatically clear the cache whenever you close Internet Explorer 6.
Go to the Tools menu, and click Internet Options.
Click the Advanced tab. In the "Settings" box, scroll down to the section labeled "Security," and click to check the box next to the "Empty Temporary Internet Files folder when browser is closed" option. Click OK to finish. This option does not delete cookies, but it will clear your cache of other files when you close your browser.]
