The preview image turns the bright areas white correctly, both in the preview
and when I apply the change (press OK). Once I've done so the image looks the
same as the preview (correct), however the indicators don't work.

In fact in the main Image Editor window, the under- and over-exposure
indicators (at the bottom right of the screen) are disabled, greyed out and
can't be clicked on. I can enable the under-exposure indicator using the F10
key, and both indicators using the entries in the View menu (at which point the
buttons stop being greyed out and can be clicked on). The indicators don't work
correctly however, they behave the same as in the white balance preview:
* The under-exposure indicator shows a few pixels, but not enough and in the
wrong place. They do have some relationship to the image however, because they
move depending on the image you have loaded.
* The over-exposure indicator doesn't appear to do anything at all, even with
obvious over-exposure (which shows up in older versions quite happily).

I will attach the three screen shots - the image when I first load it, the
image when I apply +1.5 stops correction and ask for over-exposure indication
in the 1.0.0 stable release, and the same image doing the same thing in
1.0.0-beta5, which is what I consider to be the "correct" behaviour.
