Hmm... mixing different libraries is always a quandary.

I have now had a look at your code and have made it all "jQuerified"  
so it now works.

I've actually done it two ways...

1)

I removed references to Lajax and called JT_init on document load:

$(function(){
		JT_init();
     });

this takes care of the first tootip on the original page.

I then use the "load" jQuery function to load "ajaxpage.html" into  
the "getDiv" div calling JT_init  as a callback:

<a href="#" onClick="$('#getDIV').load('ajaxpage.html',function() 
{JT_init();});"> link here</a>

This now works fine in FireFox, although there appears to be an  
artifact (the tooltip header) in safari.

2)

I called both JT_init and "preloaded" the "load" event (attached to a  
"p" tag) on document load:

	$(function(){
		JT_init();
		$('p.getDiv').click(function() {
		$('#getDIV').load('ajaxpage.html',function(){JT_init();})
     });
	return false;
}
);

Which basically says... when you click the "p" tag with a getDiv  
class, do the jTip stuff.

So when you click on the paragraph text, the div is loaded.  I  
haven't done anything to alert the user that this paragraph is  
"clickable"!

The benefit of this way is that you can send different pages into the  
load callback, (based on some criteria in the "p" tag)

I briefly covered a way to do this in my DevCon presentation (INT610)  
and the code can be found in folder "20".  You'll need to digest  
"final.php" (the page that is called),  "pubs.php" ( a loaded div)  
and "articles.php" (the different "tooltips" that are called) to make  
sense of it.

One last thing... If it were me, I'd be working in only one  
Javascript library, unless you have been given code that works  
solidly and you need to extend it.

I don't know if this list supports attachments so have sent this  
email back channel as well.  If anyone wasn't at DevCon and wants a  
copy of the presentation files, please let me know.

Regards

Michael Ward
