This release adds Lightbox / Slimbox and Shadowbox conversion (convert any lightbox / slimbox or shadowbox popup link into a JCE MediaBox one) as well as fixing a few bugs, most notably an issue with IE6 / 7 detection and browser title tooltip display issues in IE.
Included in this release is a new option to create popups on the fly, on content loaded by ajax for example, by using the jcepopup.create(elements) method (where elements is an array of potential popup links)
