SDI system variable
Single-document interface (Windows)
Controls if a drawing is opened in a new application instance or an existing instance. Partially implemented: SDI variable controls double-click behavior for drawings, but it is still possible to open multiple documents in each application instance.
Note: SDI setting 2 and 3 are not saved. If SDI is set to 3, the program switches it back to 1 when the application that doesn't support multiple drawings is unloaded.
