This is the smallest test case that, will exhibit this problem.
<html>

<script language="JavaScript">
<!--
p1on = new Image(35,35);
p1on.src = "/images/txtanim.gif";
// Javascript End -->
</script>

I have setup a page with this on my machine, this page has no content just a
java script.

The problem seems to be a bit more insidious. Preloaded looped animated images 
(done via a new Image() in JavaScript) continue looping even if they are not 
displayed. We seem to be leaking during the looping at a pretty scary rate. 
Preloading images is fairly common (doing it with looped animated images less 
so).

Using a depend build from today (3/9/00) on Windows NT, the memory problem seems 
resolved. Memory use continues to go up but at extremely slow pace. There must 
be another place where memory is leaking.
