There are some small compatibility problems with jquery-1.4.1.js/jquery-1.4.js in jqModal.js and jqDnR.js. One have to replace in jqModal.js and jqDnR.js the text “$()” with the “$(document)”. This problem is described, for example, in http://forum.jquery.com/topic/…..jquery-1-4. Without such changes jqModal and jqDnR works incorrect together with jquery-1.4.1/1.4.
