JCE Utilities Mambot 1.1.5 has been released and is available now in the downloads section.
This release sees the mambot move from using mootools as its javascript effects library to jQuery, partly because of unavoidable conflicts between mootools and prototype/scriptaculous (which is used by many other Joomla mambots/modules). Unfortunately this means that the popups will no longer be draggable (they may get this functionality back in the future), but a number of new configuration options have been added to the mambot, including the ability to have a 'semi-transparent window overlay' like in the original Lightbox.
 'Operation Aborted' issues in IE6/IE7 should also be fixed. Furthermore, both the jQuery script and the JCE Utilties script are compressed for quicker loading (the original source files are included.
