Changing thickness of a line drawn with Line Tool [in PS 2017.1.1]
Hi,
I am using Photoshop 2017.1.1 Release. I have been using the Line Tool to draw line segments. Sometimes I choose to put an Arrowhead at the Start or End of a line segment. I have not been using it for very long, but I am pretty sure I remember being able to change the thickness of my line segments by changing the value where I have circled in blue below...

... today, changing this value does not seem to have any effect that I can notice. If anyone can tell me what I am doing wrong, I would greatly appreciate it.
Thanks in advance,
Paul
