I want to use a custom javascript file and I have created the new file with some modifications to the hover node function.  I want to use this new javascript file for my UltraWebtree controls.  I have created a new folder App_JavaScriptFiles and have placed WebTreeModified.js inside of this folder.  I select the webtree and change the JavaScriptFileName to point to the WebTreeModified.js file but the control is still using the default javascript file.   Anyone have any suggestions on why this is being caused?
