Using multiple Jquery components having different Jquery versions.

Using multiple Jquery components having different Jquery versions.

I am using combobox component of Jquery http://jquery.sanchezsalvador.com/jquery/page/jquerycomboboxexamplealternatestyle.aspx and my existing page is already using jquery 1.4.2 and flyout component of Jquery.

When I am adding the combobox component using   jquery-1.1.3.1.js, jquery.dimensions.js and jquery.combobox.js". My flyout menu and other Jquery functionality stop working.

Is there any solution to resolve this problem? I have tried jQuery.noConflict() as well but it doesn't seem to be working. I need the solution at the earliest if someone can quickly help.

Thanks.
