Is there away to overcome > it? e.g. by making a copy of the Image rep before unlocking? Would it be possible to render the image of the icon and the badge into an NSCustomImageRep? This is how I am writing the icon in TimeMon. In fairness though in that code the icon is written as a series of Bézier curves.

I think this might be one of those differences we need to accept, unfortunately. It might be possible to write some code that will work on both while sidestepping this limitation.
