The calendar icon for the date field does not display in IE 9 without having the user select compatibility browser. This also removes the functionality of the date field, requiring the user to type in the date manually. By using Adobe Forms Central, we have streamlined our form submission process, but without cross-browser compatibility we cannot provide an easy to use solution for our users.
While I have found a temporary solution to resolve the issue for effected users, it would be great if Adobe would resolve this issue.
The calendar shows up well for me in IE9 with or without compatibility mode on. Does it happen to all your forms or just a particular form? If it happens to all your forms to you, can you please try with IE9 on another computer?
