I have this
<DIV id="canopy" onClick="myhand ler(event.x,eve nt.y); return false;">
<IMG border=0 height=66 width=292 src="gifs/top.gif">
</DIV>
which works in IE. myhandler gets called with the coordinates of where
the mouse was clicked relative to the <HTML>, and I know where my DIV
is, so I can calculate which part of the image was clicked on.
But with Mozilla, I can't use event.x and event.y, only event.screenX
and event.screenY. These are relative to the whole screen, and so are
affected by the positioning of the browser window and the amount of
browser chrome, so I can't translate them to the frame of my image.
Is there a simple way to deal with this? A Google search leads me to
pages like http://www.mozilla.org/docs/events.html which I am not able
to understand.
The best I can come up with is to create a bunch of empty ("visible" but
transparent) layers that sit in front of my "canopy" layer and catch the
mouse clicks.

You surely missed
event.clientX, event.clientY.
Do not use event.x - its obsolete and IE only.

The section of the Mozilla site you were after is:
*DOM Reference*:
<URL:http://www.mozilla.org/docs/dom/domref/>
*Event Reference*
<URL:http://www.mozilla.org/docs/dom/domref/dom_event_ref.h tml#998197>
Where you will find references to W3C DOM properties clientX/Y
and screenX/Y and the older, non-W3C layerX/Y, pageX/Y.
If you are doing stuff with coordinates, the "Viewport" link at
quirksmode.org is an invaluable reference:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
