&gt; Hi,<br>
&gt;<br>
&gt;  I have a web page which contains some machine-generated (from Haskell<br>
&gt;  for the curious) Javascript. This page displays an entry field, and<br>
&gt;  each time a number is typed, and Enter is pressed, the number is<br>
&gt;  converted to roman and printed above along with the time it took to<br>
&gt;  convert it. This is my &quot;canonical&quot; test program of the Haskell<br>
&gt;  converter.<br>
&gt;<br>
&gt;  The page is at <a href="http://www.golubovsky.org/repos/wsptest/EchoM.html">http://www.golubovs<wbr>ky.org/repos/<wbr>wsptest/EchoM.<wbr>html</a><br>

&gt;  It works fine in Firefox, but leaks memory terribly in MSIE. I am<br>
&gt;  trying to find out the reason: where is that circular reference that<br>
&gt;  prevents objects from being GC'd.<br>
&gt;<br>
&gt;  Is there any free (not necessary open-source) tool specifically for<br>
