I was able to customize the regular listbox control to get the large wide scroll bars for my touch screen. This does all I wanted to do. See screenshot attached. Now the operator can do everything without a keyboard (from touch screen). The problem is that after I save the VI, and then run it again, the listbox scrollbars have reverted to original size (see the other screenshot). I tried saving it as a control, typedef, and strict typedef, and checked automatic from typedef in the properties of the control, but nothing prevented it from reverting back to the narrow scrollbars. Does anyone have any suggestions?
