There are a couple of possibilities here.
Search your system for the DWORD (registry value) 'nobrowseroptions'
If the value of 'NoBrowserOptions' is set to 1x0 ... remove the value or set
to 0 (0x0) to return the system to 'normal' operation
If no joy, a file called inetcpl.cpl (Internet Control Panel) file may be
damaged or corrupt and needs to be replaced. Try replacing it with system
file checker.
If you installed Spybot, turn off "protect IE control panel".
