I've noticed a little peculiarity about my standalones. The Quit button (the one next to the minimize and maximize buttons) doesn't work standalones in max 5. I thought it was just the win app, but a user just pointed out that mac apps don't close either. They both will close only by selecting quit from the file menu.

For your information, that button on a mac is for closing a window. On windows that is the same, although it's hardwired to quitting the app, so it seems. When building a mac app, it's possible to enable closing the toplevel patcher through the standalone object.
