Barometer indicator always blue

I have WWL 7.0.96 and find the barometer indicator always seems to be blue, as in steady, I have never seen it turn red for falling or green for rising?

Most weather stations outside of the US do not report the rate of change for pressure. I am working on adding a feature that logs all downloaded weather data. I’m going to use that data to figure out the rate of change for the weather stations that are not currently reporting it.

Thanks Mike for your product and usual prompt replies. Thanks also to the private weather stations in Christchurch for maintaining weather info after the earthquakes here over the past year and subsequent 9000 odd after shocks since Sept 4 2010. =D>

Exactly Barometer indicator always should be blue.

My barometer is always blue regardless of the weather station I select.
