I have sent an application for a job in Careers. Now if I enter the "Messages" section and go to "Sent - Applications", I can see that below my application there's a grayed out text area to type a reply, together with the "You must wait until the employer responds to your application" message. All OK and logical.
The strange thing is that although the "Send Message" button is disabled as one would expect, the "Attach File" button is enabled and working (the browser's file selection dialog appears):
This looks like a bug to me... or has it any real purpose?
