Details
Try out this test case. When it isn't absolutely positioned, it works fine. But
when absolutely positioned, my handler is called twice for each mousedown
event.
Here's a test case:
<html>
<head>
<script>
function handle(e) {
var myp = document.createElement("P");
var mytext = document.createTextNode(e.type);
myp.appendChild(mytext);
document.getElementsByTagName("BODY")[0].appendChild(myp);
}
</script>
</head>
<body>
<p onmousedown="handle(event)"
style="position: absolute; left:200px; top:200px; width: 150px;
background-color: #cccccc;">
The event will appear in a unique paragraph for each mousedown event.
Press your mouse down on me to try it. If you see 2 paragraphs, that's
bad. If you see one, that's good.
</p>
</body>
</html>

The events were being dispatched through both the view and frame hierarchies
and therefore hitting the target twice. The proper route should be through the
view route. I've commented out the route through the bodyFrame and once these
frames have a separate list of their absolutely positioned kids we just have to
not dispatch through them.

Pinged originator yesterday for verification of bug; unable to determine whether
the behavior in the 12.1.98 build is as expected.
(Specifically, clicking on the paragraph results in the paragraph's layout
becoming completely munged, and row after row of "onmousedown"s in the left-hand
portion of the page; I guess the 'onmousedown's are technically in separate
paragraphs in an HTML sense, as there are line breaks between them, but I'd
rather defer to reporter on this one.)

I'm not seeing any munging of the paragraph contents at all. For each time I
click on the parapgraph I get a single "onmousedown" appearing on the left side
of the page, each beneath the next. This should be the intended behavior.
Could you describe the paragraph munging more?

Hi, Tom ---
Sure. The munging starts the moment the first "onmousedown" is drawn that
results in the need for the viewer to scroll downwards. (Still using xpviewer,
12.1.98 build on Win NT 4.0 SP3)
If you partially cover up the column of "onmousedown"s with another application
(in this case, Communicator 4.5) after this munging has occured and then return
to it, the portion of the "onmousedown" text that the viewer redraws is
vertically offset.
I'll send you a .BMP file by E-mail illustrating both of these points, to make
this easier.

BTW --- I've noticed that it only appears to happen if you shrink the window a
bit (say, 250 pixels vertical space for the viewer's content region.)

I've reassigned this to kipp@netscape.com as a new bug (#1756). I don't really
want to clutter this one up any further as the defect is separte and not
related to this original bug. So I think we can verify this.
