I think Frank needs to be posted in our Mac Debugger Hall of Fame. For one
that bug has been around for 7 months and secondly, we need someone in that
Hall, it's empty.

Subject: [Dynapi-Dev] Mac bug & fix....
In this article:
http://www.geocrawler.com/archives/3/7119/2000/11/0/4715441/
(fron last year)
Two people we're discussing a bug with getContentHeight in IE5 for the
mac.
Well, a partial work around was suggested, and then according to my
search nothing else was ever discussed. I just ran into this bug using
the label.js class with IE 5 Mac. Six hours of my life are forever gone
and wasted using DynAPI.console.write() and a Mac (bleh) tracing this
very same bug down in my code. I really hope someone takes this patch
and implements it so that noone else is left tracing the same bug for
the bettter part of a day.
Details:
this.elm.scrollHeight in IE 5 Mac returns NaN if the content doesn't
overflow the div. this.elm.offsetHeight is the same height as
non-overflowing scrollHeight (see:
http://msdn.microsoft.com/workshop/author/om/measuring.asp for pretty
pictures of what all these CSS properties mean) and thus a vaiable
workaround is:
"else if (is.ie) return parseInt(isNaN(this.elm.scrollHeight)?
this.elm.offsetHeight : this.elm.scrollHeight));"
in DynLayer.prototype.getContentHeight
Upon further testing, i found a somewhat intresting bug that leaves us a
second choice to patching this. If you access the elm.offsetHeight
property BEFORE access elm.scrollHeight then scrollHeight has the proper
value (scrollHeight = offsetHeight). This is vaguely reminiscent of an
old NS bug, where values of CSS properties would not fill in until after
you access them or other properties in a certain order. Anyhow, another
solution, possibly better (???) than the previous is this:
else if (is.ie){
this.elm.offsetHeight //Mac hack, forces scrollHeight to fill
due to IE 5 mac bug
return parseInt(this.elm.scrollHeight);
}
Comments? suggestion?
BTW, anyone know of a JScript dbugger on the Mac that hooks up to IE 5?
it's insane tracking down bugs w/o the ability to see a call stack, or
trace.
