I did a test of ghost hourglasses while dragging an image in IE 5.5:
// Only the A gif does not have a ghost hourglass.
// A= gif added with setHTML, with the layer added the long way.
// B=
gif added with setBgImage, with the layer added the short way.
// C= gif
added with setHTML, with the layer added the long way.
// D= gif added with
setBgImage, with the layer added the short way.

No, I am not being cynical, I really worship you guys, and what you can
make a web page do. I can only try to emulate some of it.

I so glad this is being discussed by the coding gods. Inquiring
minds want to know.
I'm hoping your
being synicall here ...
Anyway, there
might be problems on IE5.5 machines when you have empty-layers, I haven't
tested this, but I got thinking that there's a dummy-image placed into the
background if a layer is empty on ie5.5 (this to fix the bug with
events not triggering) This might also mean that if this layer is
moved/resized/whatever the hour-glass appears because it want to load
the dummy image.
Not sure if this
happens, because the image is actually
javascript:null so it should not try to load anything at
all.
The problem with
NS6 is a problem in the eventlistener.. I think Jordi fixed this problem for
IE, and seeing that most things work the same under IE5 and NS6 the same fix
should be possible for NS6 (problem is that the image receives the event,
and this screws up the layer's event handling because it can't recognise the
IMG's layer object parent)

Some feedback... I get the same ghost hourglass while dragging
images added with both setHTML AND setBgImage on my 200 meg
machine.
I have started using setBgImage because ns6 doesn't drag an image
added with setHTML, unless I put an empty layer handle on it.

Doug,
breath in, breath out...
It's very obvious that the pressures of
your sites pending deadline are leeching into your tone and tenor within
the group.
We all learn here, every day. It's
one of the profound benefits of being involved in this type of
collaboration.
To expect a literary manifest of total and
absolute wisdom in a field of endeavor as complex as this is asking a
tad much; even from the notables we have the privilege of working with
here.
The truth be told about setBgImage is that
the bug was with NS when using "events" and setBgImage together.
There is no bug in IE what Pascal is referring to is an "optimization"
and "efficiency" as related to a interactive game.
Now, that said.. where's my friggen "rock
at!

THIS is why we need a more
full attempt to document the DynAPI.
I have at least 15 calls to
setBgImage().. noone told me IE had a weekness here...

I do agree here.. I have
fond that in the widgets I've played with, and in the examples I seen
there has been way too much of the "better mousetrap" syndrome.. In
fact I almost exclusivly use DynLayers now..
except in the rare
occations where I need to 'pack' the hight or width of an object (read
Label())

again.. COMPRESS your graphics.. This CAN be
achieved without loss of image quality..
