I've ran into a problem with editing custom shapes (made with the Paintbrush Tool). After making the shape, I was using the Free Transform Tool to edit the stroke curve shape of parts of the custom shape I made (without changing the scale of the stroke). After a while, when I used the Free Transform tool to edit the parts of the custom shape, it keeps on changing the scale of the stroke as well, without even curving the part of the shape (even with the curve and corner shape part indicators near my cursor when hovering my cursor over the parts of the custom shape).
Is there a setting to lock the width of the stroke of a shape in place, to enable transforming of the shape without affecting its stroke scale??
