If any Internet Explorer users tried, but failed, to draw tracks on
a Google Map using GPS Visualizer in the last couple days, please
try again. It turns out one has to jump through a few extra hoops
to get IE to display tracks in Google, and I didn't have those hoops
formatted exactly right.

Hopefully everything should be OK now:
