When one or more items are selected in the subitems table, the menu items under the
button "More actions" should appear. This does not work with JQuery 1.4.4

When modifying the following settings in ezjscore.ini, everything works again:

1. enable / disable loading the YUI / jQuery files from external servers
   -LoadFromCDN=disabled
   +LoadFromCDN=enabled

-ExternalScripts[jquery]=http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js
+ExternalScripts[jquery]=http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js
