Subject: Re: FLASH: Onload event interfering with DHTML Hierarchial menus
From: Jon Williams
Date: Fri, 14 Jul 2000 15:07:42 +0100

this stuff can be messy. Javascript can't have threads, so
it's possible to end up in nasty situations like this.
Without knowing which mouse events are being tracked,
it's hard to say, but there are a couple of general techniques.

1) Instead of onload() you can drop the following at the bottom
of a page prior to the </body> tag and it should work

<script language="javascript">go()</script>

this will probably screw up if your scripts are located in
externeal files...therefore this is not as reliable as onload, but...

2) If your onload functions run and then stop (ie. don't keep
any loops running for updates) then you could modify your
menu dhtml to wait before kicking in the event handlers.

3) If by some small chance this problem is being caused
by needing to kick off two onload functions, create a new
function "uberonload" and drop whatever function calls
in whatever order into that function:

function uberonload() {

onloadOne ();
onloadTwo ();

}

4) Use www.dansteinman.com for your dhtml API. I've not
had complete success with the code available from webreference.
It tends to not be as well tested cross-browser IMHO.

hope that helps..javascript is evil this way.
