10.3.8 Non-refreshing temp sensors

Hi
I downloaded Temperature Monitor 2.5 from VersionTracker and noticed that it states that the latest version of Mac OS X does not refresh the temperature sensors, so - unless I am reading this wrong - you only get the temperature as the machine is fired up. Certainly I've noticed that the gauge value does not change in the Dock.

Does anyone know if there is a solution out there?

If this is in the wrong section then I apologise but at the moment I'm not sure whether this really is a hardware issue or a software issue.

Is anyone using a temperature sensor utility successfully on a new powerbook running 10.3.8?
