Thought this might help someone else. In trying to use the Tooltip plugin I was having issues using the documentation found here - http://flowplayer.org/tools/demos/tooltip/. The Javascript coding gives the example $("#demo img[title]").tooltip();. I found that because of the drupal.js script I needed to change this to jQuery("#demo img[title]").tooltip(); and it would work. In other words, replace "$" with "jQuery". The full script file would look something like this 

jQuery(document).ready(function() {

jQuery("#demo img[title]").tooltip();

});

Hope this helps another novice like myself.
