Can you give an idea what the other reasons are? >This works perfectly except for a single little problem.

As a guess, I would try forcing the traffic light buttons to be enabled. NSWindow's standardWindowButton: method would give you the buttons. I'm uncomfortable enabling the close button when a window is displaying a document-modal sheet, but I'll leave that for people who are better at being HIG police to comment on. I don't know if your pseudo-sheet is resizable, but if so, remember that real sheets stay centered horizontally within the parent window. Note also there's a slight shadow at the top of a real sheet. For verisimilitude you might want to reproduce that shadow, bearing in mind that if Apple changes the appearance in an OS update you will then have a non-standard look. Without knowing more about why you can't use a real sheet, I still wonder if you could make it work (assuming you can force the red close button to be enabled). There was a thread here recently about reducing the amount of time it takes for a sheet to slide down. Maybe you could set that to zero and apply your own fade-in and fade-out. If you get really stuck making this work, could you give up the idea of looking like a sheet, and use a view that appears in the middle of your window, on top of everything else in the window? There are ways to hijack mouse clicks and keystrokes so the rest of the window is effectively disabled. One thing you'd lose is the ability to resize the window smaller than the "sheet."
