Is Internet Explorer Scroll Bar Missing?
If you are using Internet Explorer 6 and earlier:
* Click on the Restore Defaults button and follow the on-screen instructions
If you are using Internet Explorer 7 and 8:
* Click on the Reset... button and follow the subsequent instructions. Various security settings, privacy options, pop-up settings and toolbars and add-ons will all be reset with this option, while information such as home pages, web forms, passwords, history, cookies and temporary Internet files can be removed in the Reset Internet Explorer Settings confirmation dialogue box.
Confirming this command should resolve your scrollbars issue, but note that information can be lost – resort to this option only when your browser is in an unusable state.
