Graham, You said, "you close the sheet itself by sending -endSheet to the SHEET, not its parent”. Correct me if I am wrong, but I think you send endSheet: to the parent window, with the sheet window to be dismissed a parameter. Same for the deprecated NSApp method of the same name.
The doc says: - endSheet: Ends a document-modal session and dismisses the specified sheet. Declaration OBJECTIVE-C - (void)endSheet:(NSWindow *)sheetWindow Parameters sheetWindow The window object that represents the sheet to be dismissed.
