I noticed two small bugs regarding dimming of all lights except for the home airport (if this feature is used).  One is in the Configuration Editor, where the setting description shows the range as 0-255.  In reality, this setting goes from 0-100, where 0 isn't dimmed at all, 30 would be dimmed 30% compared to the home airport, and 100 would be 100% dimmed (totally dark).

The other small error is in metar-v31.py.  Under the section on dimming (def dim(data,value)), the line that dims the blue value needs a slight change to this:

blu = data[2] - ((value * data[2])/100)

It was multiplying by data[0] instead of data[2].  Only showed up when certain colors were being displayed, and then the dimming wouldn't work correctly.

Such a cool program, and documented nicely enough that amateurs can figure it out.

Thanks!
