In an ExtJS 1.1 app with 5 data grids - user wants to see only one vertical scroll bar (scrollbar for the dialog). Is there any way to force grid to grow instead of scroll?

I desperately need this otherwise I will be forced to abandon months of work done in ExtJS and go back to straight HTML.

I have managed to increase the height by hooking onto to "load" event of store but there are 5 grids and increasing height of all grids causes severe performance hit; secondly grid doesn't render correctly after increasing height of the container until resize event is fired.

Your ideas / suggestions are greatly appreciated.
