How to change the scrollbar width of a multibox?

[#1]

Hi, I created a multibox object, right clicked on it, navigated to Properties > Layout and adjusted the "Scrollbar Width" field but it didn't take effect. Did I miss some step to make it work? Changing the colors of scroll buttons & scroll background didn't work either although it worked on a list box object.

My Desktop QlikView version is 11.20.12451.0 SR7 !

In SR6 64bit, width and color works, may be someone else with SR7 can check

Thank you. Now I understand how the option worked. But what I wanted is to change the scrollbar width of the drop-down box that appears when I select a field within a multibox. Is there an option to do this?
