Using jstree with jssplitter

Using jstree with jssplitter

Hi,
I can not use jstree with jssplitter with 4 pane. I have a vertical splitter splits into left and right and each has horizontal splits. In left top I have a jstree just like a folder explorer in windows and in left bottom i have text boxes. In right top i have a grid and in right bottom i have labels.
With this layout, if i try to drag the vertical splitter it adjusts the height and width of the left pane in IE. In FireFox it splits the window but not resizing the height and width for dragging. Any one help me to solve this issue.

Thanks
