after that it will get it fast enough everytime.

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..

not sure what you mean, but I think that resedrawing the image
