So, there's a small map embedded on the page and a larger version of
that map available when clicking the link.

This works nicely in Firefox, but the map is gray in IE, and the link
won't work at all. It appears that IE doesn't know about global
variables, because when I make the map variable local, the small map
works. The large map doesn't work, because this variable needs to be
global.

I'm also using the excellent MarkerTracker (seen on the API blog) add-
on. It works as expected in Firefox, but in IE, it sometimes leaves
tracks so that there are more than one markertracker on the map!

IE sometimes doesn't like variables declared without the preceding
"var".

That is, you should have:

var map = new GMap2(document.getElementById("map"));

Try that, to see if it helps.

IE does peculiar things deciding what becomes a global variable and
what doesn't (especially if you have variables with the same names as
elements). Explicitly declaring variables makes it behave in a
standard way.

// Place marker
var opts = {};
var marker = new GMarker(center, opts);
map.addOverlay(marker);

In particular, it appears to be the empty array in the constructor.
The constructor needs a variable there, and I have no options to give,
so I figured an empty array would be alright. Is there another way to
write the same that doesn't cause the error in IE? The error is simply
"Unknown runtime error."
