yeah, and it looks like NS6 has inherited this problem.  we managed to get
NS4 dropped from the requirements for this project (woo woo!  progress!), so
75% of the madness has dropped away.  still, this height bug remains.

that's similar to what i just tried, and it seems to work.  specifically, i
have an abs-DIV with a variable height (this is all going into a template,
so the contents of the DIV is dependent on the content for the specific
page), and i need a table behind it to "stretch" so that a TD "fits" the DIV
in terms of height.  so i stuck a rel-DIV at the bottom of the abs-DIV
(inside it, after the included content), then stuck a blank placer image
inside that rel-DIV.  calling the image's .offsetTop value gives me the
bottom of the abs-DIV (relative to the abs-DIV itself), which i can then use
to get the *height* of the abs-DIV.

whew.

in rereading this, i'm wondering if i need the rel-DIV at all...

FWIW, then i'm applying that value to an image in the TD that's supposed to
"stretch" around the DIV.  this forces the TD to grow to the height of the
DIV (which is necessary, because there's more content below that needs to
flow around whatever's inside the abs-DIV).

if any of that made sense, i'll be amazed...  8)
