We're going to need some more information in order to be able to help you out here. In another post you were talking about the keywords panel, where autocomplete is not available (though it is likely we could add that ability). Is that what you are referring to here? Or are you referring to the keywords field in the Metadata Info or Metadata Template windows, then please provide some more detail: What operating system are you on? What are your Autocomplete settings? What is an example of something you are typing into the keywords field and what are you expecting it to auto fill when you type that in? Are other fields in the Template or Info windows auto filling, and the problem is strictly the keywords field?
