Try the following code. First select an option. The alert is triggered. Good.
Then scroll the select box. The alert is again (and each time) triggered. This
is not good.
<html>
<body>
<h2>Test</h2>
<p>First select an option, then scroll the select box.</p>
<select size="5" onchange="alert('changed')">
<option>a</option>
<option>b</option>
<option>c</option>
<option>d</option>
<option>e</option>
<option>f</option>
<option>g</option>
</select>
</body>
</html>
Reproducible: Always
Steps to Reproduce:
From http://www.w3.org/TR/html401/interact/scripts.html#h-18.2.3
The onchange event occurs when a control loses the input focus and its value has
been modified since gaining focus. This attribute applies to the following
elements: INPUT, SELECT, and TEXTAREA.

Edwin, you are using a 3+ months old build. The guidelines
"bug writing guidelines"
http://www.mozilla.org/quality/bug-writing-guidelines.html
recommend a 3 days old build for reporting bugs.
"be sure that you've reproduced your bug using a build released within the past
three days. Our development process moves at lightning speed, and the bug you've
found may already have been fixed."
Also, you should have searched for a duplicate. Here, bug 207637 description
meets exactly this bug description. If the problem was still happening with a
recent build, then requesting to reopen bug 207367 was the thing to do.
Finally when you want to submit a reduced testcase (and this is welcomed), best
is to use the "Create a New Attachment" link to do this.
FWIW, your testcase WFM with Mozilla 1.5 build 20031007, XP Pro SP1.
