A resource with the ID you have entered below the “Signature” field (‘^0’ ID=^1) does already exist. Do you want to replace it? A resource with the type you have entered in the “Signature” field (‘^0’ ID=^1) does already exist. Do you want to replace it? File types and “Signatures” are 4 character codes. The character you have just typed would make this field longer than 4 characters. Sorry, but you can't enter any more characters into this field. The character you have just typed is not a numeral. Please enter only numeric characters into this field. The value you have entered into this field is not unique. Please enter a value that is not being used in any other row in the list. Warning: You have changed the resource ID of the signature resource in the extended view to a non-zero value. This will cause all versions of the Finder before System 7.0 to ignore this BNDL resource.
