The refresh button and text should be more clearly associated with the CAPTCHA image, rather than the text box.
See https://en.wikipedia.org/wiki/File:Screenshot_of_CAPTCHA_with_refresh_button_on_edit_form.png for the old behavior.
Note that the solution should be tested to ensure it doesn't cause regressions to the new account creation screen (with VForm), which does some rearranging of this part of the interface. See https://commons.wikimedia.org/wiki/File:Account-Creation-Mockup-ByTheNumbers.png for what this looks like (a possible candidate UI for FancyCaptcha itself).
