Thumbnail size slider question

I have buttons set up to appear with the slider when in thumbnail view. If dual listers is on and only one lister is in thumbnail view and has focus the buttons and slider both appear but if focus is changed to the lister not in thumbnail view the buttons will disappear but the slider remains. Tried this


to try and hide the slider but does not work. Is it possible to do this ?

I don't think there is a way to do that, at least currently.
