Platform-Specific Compatibility Issues

Windows SDI vs. MDI Interface

Max uses the Windows SDI (Single Document Interface) model, where each window has its own menu bar. Older versions of Max (version 4 and earlier) used the MDI (Multiple Document Interface) model, where there is an overall frame around all the application's windows, and the frame contains the menu bar. In the SDI model, closing all windows will quit the application. In the MDI model, you can close all the document windows but you must explicitly choose Exit from the File menu to quit the entire application.
