[jQuery] Accordian not sliding out when specifying autoheight:false

[jQuery] Accordian not sliding out when specifying autoheight:false

I have been trying to implent an accodian that requires a click to open and a click to close.
This is working fine here:
<a href="http://jamespfarrell.com/dev/consult3fixedheight.htm">http://jamespfarrell.com/dev/consult3fixedheight.htm</a>
.... all of the divs that contain the data are being returned as the same height as the largest of them all...
so I added auto height false, which you can see here:
<a href="http://jamespfarrell.com/dev/consult3fixedheight.htm">http://jamespfarrell.com/dev/consult3fixedheight.htm</a>
As you see everything works now but the new active frame no longer slides when clicked, it just appears.
I slides if you click the same one twice, but it jumps if you click a diffent link.
does anyone know what's causing this or how I can work around it?
