Hello all,

I'm trying to draw a series of polygons that represent zip codes in
Google Maps using KML as the data source.

I'm running in to a problem where some of the polygons are drawn
incorrectly on occasion.  It looks as if the lat long points are out
of order, but they are not.

Here's the weird part, if I refresh the Google Map after 60 seconds,
the polygons are drawn correctly.  The KML data did not change between
requests.

Example:

1. Navigate browser (I'm using Firefox 3.5.3/IE8) to http://maps.google.com
2. Enter the following in to the input box and click "Search Maps":

http://205.160.15.56/GetMarketAreaKML.aspx?MarketAreaID=447

3. When the map was first drawn, it looked like this:

http://205.160.15.56/GoogleDrawBug.png

4. Wait at least 60 seconds, then click "Search Maps" again, which
then redraws the polygons correctly:

http://205.160.15.56/GoogleDrawBugFixed.png

Again, the KML data specified by 
http://205.160.15.56/GetMarketAreaKML.aspx?MarketAreaID=447
did not change between requests.

If you try this and your map looks like the Fixed version, feel free
to try a different MarketAreaID until you see some polygons that look
crazy for a zip code polygon.

Long straight cutting lines such as the ones seen in
http://205.160.15.56/GoogleDrawBug.png stand out pretty well in most
cases.  If you think you found one that is drawn in correctly, just
wait at least 60 seconds and click the "Search Maps" again and see if
it changes.

Hopefully someone will have some insight as to what is going on here.
Any help would be greatly appreciated.

Thanks in advance,

Matthew
