Problem with liquid layout and browser height

Hi,

We are currently using Vaadin(ver 6.7.2) portlets in a Liferay(ver 6) container and noticed issues with vertical scroll bar and browser height. Ideally we would like the content - such as table to expand taller to fit the browser window and the scroll bar appears only within the control and not the browser window. The vertical browser scroll bar doesn’t support our liquid layout rules and we are looking for a way to get rid of it. The content should expand/contract based on the height of the browser without the vertical browser scroll bar.

BTW - The horizontal scroll bar doesn’t appear.

We are using a combination of the following layouts on the most portlets:
VerticalLayout
HorizontalLayout
CssLayout
AbsoluteLayout
CustomComponent

Are there specific rules that we need to follow?
Any advice is appreciated.
