Recovering from errors

reports errors by displaying a message in the window or in a dialog box near the top right corner of the screen. In the latter case there are two types of error dialogs:
  1. Warning messages appear in a box with a single Continue button.
  2. Fatal messages appear in a box with a Quit button (which will quit ).
Most errors, particularly the serious ones, are accompanied by a beep. Let's now look at the most likely errors you'll encounter and what you can do to prevent them recurring.
