It is impossible to know the content's size before adding the layer to the
document ( which can be done by adding the layer to the doc or to a layer that
is added to the doc ). Before adding a dynLayer to the doc you only have a
DynLayer object and a string containing some HTML. Once the dynalyer is added, a
physical, browser-specific layer is created and its content set. At this point
the browser renders the html (either this or crashes) and from this point on,
since the browser has already drawn your content, you can retrieve its size.
Regarding the described bugs, again I can't run NS6 but I remember some post
saying that it could be fixed by using the setTimeout trick.
