Outstanding Bugs

  1. Issues with the Idle Command Pop-Up

  The Idle Command Pop-Up has a number of deficiencies:

    * The syntax for the Timeout value is not explained -- it is an optional '~'
      prefix to add +/-10% jitter to the time, a number, and a required
      one-letter suffix (s for seconds, m for minutes, h for hours).
    * If the timeout syntax is wrong, there is no error pop-up, and the values
      are forgotten.
    * The changed values are not saved with the Save Changed Options in File menu
      option.

  A (rather large) patch to correct these problems is under development.
