Hi,
i have a Swing GUI wich is designed like below. With only 1 tab, there is no problem, but with ~ 20 tabs, the divider of the JSplitpane can only go down (with the mouse), not up.
Do you know this problem and have you any kind of solution plz ?

============================================
package dividerbug;

import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.JSplitPane;
import javax.swing.JTabbedPane;
import javax.swing.JTable;

public class Test {

    public static void main(String[] args) {
        JFrame frame = new JFrame();
       
        JSplitPane splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
        JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.BOTTOM);
        for (int i = 0; i < 20; i++) {
            tabbedPane.addTab("tab"+i, new JScrollPane(new JTable()));
        }
        JScrollPane scrollList = new JScrollPane(new JList());
        splitPane.setTopComponent(tabbedPane);
        splitPane.setBottomComponent(scrollList);
       
        frame.setContentPane(splitPane);
        frame.setVisible(true);
    }

}
============================================

TIA
