Problem with Rad Splitter bar not showing up with flash

[Christopher]

I currently have a rad splitter control with two items, a rad tree view on the left, and a flash visualization on the right.

When i click on the splitter bar and move it to the right over the flash visualization, the bar loses focus and I cannot move the splitter farther to the right, but once I move the mouse back to the left so it is no longer over the flash element, the bar regains focus and I can move it.  If i click the bar, and move it below the flash element, I can expand the splitter bar to the right.

The problem occurs in Internet Explorer 8, in regular mode and all compatability modes, but it does not occur in firefox or chrome.

Sample code for this problem is below:

<telerik:RadSplitter runat="server" ID="RsSplitter" Width="100%" Height="100%">
        <telerik:RadPane runat="server" ID="RpMenuPane" Width="20%" Scrolling="Y">

After reading the recommendations in this thread and trying them, I fixed the issue.  the LiveResize property was all that I needed to set in order for the splitter to work correctly.
