EXS 24 Logic Sampler Users Group

Hi Gang,
I just upgraded to Logic 6 and in the process lost a little function 
that I found very handy.  In logic 5 when I clicked on the blue 
illuminated EXS24 button  of an audio instrument in the 
Environment...if I already had and EXS editor window open...it 
automatically made that instance active in the editor.  Ex....the EXS 
editor for audio instrument 1 is open.  In the audio environment window 
I double click the blue illuminated EXS button for audio instrument 
2....the active instrument for audio instrument 2 becomes the active 
instrument in the EXS editor. Presently...it opens a new EXS editor 
window.  I've looked all over.  Does anyone know what to call this and 
where I find it.  Thanks a bunch
