MODx 0.9.6 RC1 rev 2440, AjaxSearch 1.6, [!AjaxSearch!]
You can see for yourself;
http://migwan.sottwell.com/ - this is the "site unavailable" page as this is only a demo waiting approval for full development, but the search works. Trust me, it still works when logged in!
I do see in the source when logged in that both the AjaxSearch and the QuickEdit are loading the same mootools.js file, <script type="text/javascript" src="manager/media/script/mootools/mootools.js"></script>
And yes, that commenting doesn’t hurt anything; it’s to block it from ancient browsers that will try to display the javascript code instead of executing it.
