In the default preferences file, there’s this bit of code:
[code]
//
// Application Behavior Settings
//
// Exiting the application with hot_exit enabled will cause it to close
// immediately without prompting. Unsaved modifications and open files will
// be preserved and restored when next starting.
//
// Closing a window with an associated project will also close the window
// without prompting, preserving unsaved changes in the workspace file
// alongside the project.
"hot_exit": true,
// remember_open_files makes the application start up with the last set of
// open files. Changing this to false will have no effect if hot_exit is
// true
"remember_open_files": true,[/code]
If you set both of those to false in your user settings, I think that’ll do what you’re wanting, though I haven’t tested it.
