Why can't I drag the line when using imdistline?

I am just trying to reproduce the example 'Detect and Measure Circular Objects in an Image' and when I type the command d = imdistline; in Step 2 I have a line that appears in the figure but cannot drag the line. Why could that be?

Hi,

It should work as expected. Check the usage section of the following link for a better reference
