Hi
Please consider: When using the Ask a Question, when text is typed into the Title, a list of possible answers is opened below. All well and good, but that list needs a 'Close' button or some other means of hiding the list otherwise, the user needs to scroll all the way down and clicking outside the list. When doing that, the user is likely then at the Details entry block *thus, missing the compulsory Tag entry field and will then most likely try to post answer/comment without the compulsory Tag and invoking that horrible warning.
All that is just so easily avoided by having a means to close the suggestion list.
