dhtmlXtree: loading... message

I've seen several KB articles from people that want to have a "loading..." message displayed when the tree is initially loading, since it can take 5-seconds. All the reponses point to attaching to the onXLE and onXLS events, however I haven't seen one example. I've tried using these events to display & hide some text in a DIV right above and right inside of the DIV that holds the tree. I am not having much success - the extra text seems to mess up the display of the tree when it's expanded - I get multiple scroll bars. I've searched the examples, and I don't see an example of doing this (display a "loading..." message when the tree is loading). Could you please provide sample code for this - I think a lot of people would benefit from this. Note: I am using enableSmartXMLParsing, and I'd prefer to not show the "loading..." message on each expand of a previously unloaded item.

Sample of usage attached to post ( please be sure to load sample by http like url, because , if you will use IE and direct file link - like c:/code.html - the behavior will change )

Events generated only for cases, when data loaded from server, so it will not be show for opening items in SmartXMLParsing mode
