Open regedit...Start > Run > type regedit
have a look for the following 2 keys.....
HKEY_CLASSES_ROOT\Drive\shell
name = Default
type = Reg_SZ
data = none
HKEY_CLASSES_ROOT\Directory\shell
name = Default
type = Reg_SZ
data = none
They should both normally have the value "none" in "default" ....
Before making changes to ure registry i strongly suggest u backup
