Remove scrollbars from Alarm Message List

Remove scrollbars from Alarm Message List

I'm working with VIPA Touch Panel with Zenon 6.22 SP0.
I've an allarm banner in the lower part of my window and when active alarms are many, the vertical scrollbar appears with its two buttons to scroll up and down the alarm list.
Since the two buttons are very small to click with a finger, I would like to disable the scrollbar and insert the line up and the line down buttons, but I don't know how to disable the vertical scrollbar.
In the editor, in the Alarm Message List element property, I can see a folder named "Scrollbar", but all the fileds are disabled.
There is a way to resolve this problem?
Thanks.
Davide
