Just tested on a PC in IE and it doesn't work there either. However, in IE I got the JS error icon in the left and corner. When  I clicked on it I got the Message: "children.length is null or not an object" Line 588 of dnn.dropdownlist.js

That line is:

for (var i = 0, count = model.children.length; i < count; i++) {            castedNode.children.push(TreeNodeConverter.castNode(model.children[i]));
}

At first I thought that might make sense. I do have a portal that has a large number of files and folders. However, I then remembered that this is happening where the component is used to select a page, and I don't believe there are enough pages to cause a timeout.

Since I have been getting very little help. I did a little more investigation. I setup a test installation of DNN 7.01.02 (My live installation was a migrated 7.00.06 that was upgraded to 7.01.02). The component in question works fine in test installation and is not throwing the JS error I'm getting in the live installation.

Is it possible the component did not get installed properly during the upgrade? If so, is this component something I can try to reinstall?

It was suggested that this might be a timeout issue due to too many folder/files/pages. If this ends up being the case is there a way to revert back to the previous component which handled this load with not issue?
