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..
