Use this option to close the database in the currently selected editing window. If you have not saved it since making changes, the program asks; "Do you want to save changes to database?" If you answer no, all changes since the last "Save" will be lost. (Shortcut keystroke: Ctrl-W). Note: Clicking the x button in the upper right corner of the edit window will also perform this close function.
You can also get a pop-up menu with the New Database and Open Database options by using RightClick in the editing window workspace, outside of the editing windows.
