Re: IE Map Error

One thing that might be worth trying is removing the extra comma from
the array of GPoints in your polyline.

Its possible that IE might be interpreting the end bit

new GPoint(174.812, -36.919),]

as if there's an extra null element at the end of the array after the
comma. When the API reads through the array, it tries to process all the
entries in the array, including the null one, which isn't a correctly
formatted GPoint(). In particular, the null object doesn't have a .y
property which the API is trying to use for the latitude of the polyline
node.
