OverlayWindowMBS can no longer be used on 64bit macOS.
I used it to make a Window transparent, which has a picture on it, a progressbar and a label.
I see that I can use OverlayMBS now and somehow mimic the behaviour of controls by painting myself, but I have hoped to find a solution which works more like the old (now obsolete) solution: use a window, drop some controls on it, make the window transparent.
Are there declares to achieve this?
