Brightness/contrast selection in grayscale images

Hi list

I am struggling to set the brightness and contrast within a selection of an image.  This works fine for 24-bit RGB images, but when attempting this on grey-scale images the whole image is windowed, rather than my selection.  It is possible to work around this by switching types, but it is inelegant and not much good when working with floats.

Is there a particular reason for this? Does anyone know of a trivial solution?

Many thanks, Neil
