UltraWebListbar inside WebSplitter does not resize smaller


I have a webform that has a horiz websplitter - "WebSplitter1".  I have a listbar (type explorer) within the lower splitter pane.  when the browser window is resized smaller, the listbar and its content do not get resized smaller - the list and content appear to remain the same size.  However, when the browser window is resized larger, the listbar and contents are resized larger as expected.  Note that when I replace the "WebSplitter2" with simple text, the listbar and contents resize smaller and larger as expected.

I have spent quite a bit of time stripping my webform page down to demonstrate this behavior.  I have provided this code below so that you can just drop it into VS2008.  Simply run this page and resize the browser window "smaller" - then "larger".  I am using IE7 and IE8. 

Q: How can i get the listbar and its content (which is another websplitter) to automatically resize smaller as well as larger when the browser window is resized smaller and larger?  Am I missing a setting on the listbar? or the websplitters? 

Thanks in advance!

    I have the same problem too. And if try to use Height 100% for listbar it gives an error in BLOCKED SCRIPT

    while(this.Element.offsetHeight > actualHeight)


    percent--; = percent +
    "%"; <<Error on this line


    If I try to resize the listbar from javascript like:

    var lst = document.getElementById('<%=uwlMainlLeftMenu.ClientID %>'); = document.documentElement.clientHeight - 100;

    It put some extra space on top of Items inside all groups


    Any suggestion?
