Rudi,

It works fine on my computer.  I am running Guide 9.0 (27 July 2015 version) under Windows 10.  When I click wider or narrower, the lines change in thickness for the five styles available.  I then click one of the styles and I get a line of the thickness and style that I chose.  You must click a style for the thickness to change even if it is the same style already being displayed.

Regards,

Tom
