Re: infinite loop when using read_mini

I just returned to the code that prompted this question and I don't seem to 
be getting this behavior. Ie, pressing ^G is generating an  UserBreakError 
exception rather than causing read_mini() to merely return an empty string. 
Eg:

define test()
{
  variable input;

  do
    {
       try {input = read_mini("type something","","");}

       catch UserBreakError: {message("caught exception!"); return "";}
    }
  while (strlen(input) == 0);

  return input;
}

Pressing ^G at the prompt produces the "caught exception!" message.

Thanks for any clarification

Marv
