Whenever lambda _min<390 or lambda_min>400, lambda_max<700 or lambda_max>830, the value shown in the spinbox is autocorrected correctly, but the computation does not terminate.
An example: When the user gives a lambda_max > 830 by means of the keyboard (try, e.g., setting lambda_max = 850 and press compute), the lambda_max value shown in the spinbox is autocorrected correctly to 830, but the computation fails to terminate.
