Sometimes when adding or removing toolbars to Internet Explorer the list can get messed up and blank lines with checks next to them will appear.

By editing and removing iTBarLayout from the Windows registry the list can be fixed. Be sure to close all IE windows before editing registry and always be careful. To access the registry navigate to START -> RUN and then type: regedit. Then find the following registry key section:

HKEY_CURRENT_USER \Software\Microsoft\Internet Explorer \Toolbar\WebBrowser\

Look for iTBarLayout along the right and delete. Then restart Internet Explorer. You may lose some custom toolbar positions or have to re-enable some toolbars.
