DzDial Focus Highlighting Removal

dyodyo

Quick question and purely cosmetic: with the DzDial control, whenever I click on it to select a dial value, there is this garish yellow 'focus highlighting box' that appears to show the control has been selected -- is there any way / property inherited to switch off the focus highlighting?

(it's the first time I've used the control on a UI, and perhaps everyone's used to the focus highlighting, it just took me by surprise)

Thanks,

(edit: probably should've mentioned I'm writing in DazScript / see attached for a picture)
