AW.UI.Tree control horizontal scroll not visible - Please help

I've been using the AW.UI.Tree control with ActiveWidgets 2.0.0. I've noticed that if the length of the text in the tree exceeds the total width of the tree control, then the tree control does not display a horizontal scroll bar to allow you to see the clipped text. The same is not true if the number of nodes exceeds the length of the scroll bar, the vertical scroll bar does appear.

Is there any easy way to enable the horizontal scroll bar?

Thanks,
Dan B.
