OK, I can live with that. How about question #2, any idea how I can do
this same thing with the new 2008 Tiger maps.... while mobile?
Thanks again...

The problem is the county names still lie under the labels of the

Aren't the station labels _always_ on top? I don' think you can
raise
the map above the station.
Correct. We do this:
1) draw maps->pixmap1
2) copy pixmap1 -> pixmap2
draw weather alerts onto pixmap2
3) copy pixmap2 -> pixmap3
draw stations & tracks onto pixmap3
4) copy pixmap3 -> display
There are valid reasons for doing it this way, mostly for
speedups/efficiencies, as most of the time we just have to do #3 and
#4, and only when new weather alerts come in do we start at #2. We
very seldom start processing at #1 except for perhaps mobile Xastir.
