Please download the latest version (v.2.5.0.2 released today) and try again. If it doesn't work, please send me the URL of your website and specify your Joomla! version and browser. Email address: see this website.
To see the immediate effect of a change in settings, it sometimes helps if you select a different station at the frontend (button below the details list).

I ment version 2.3 in the previous entry.
I reinstalled 2.3 for the time and the scroller is working fine. Why not in v2.5?

I get no scroller. Scroller is 'on', station and metar present. First updated 2.4 to 2.5, same problem. Then deinstalled 2.4 and did a fresh install of 2.5, still same problem... How come?
