When using a JComboBox as a JTable cell editor, keyboard navigation doesn't work properly. Alt+Down arrow doesn't post menu of the JComboBox.

Steps to reproduce:
1. Select the table (Note that on my system the table was
not visible until I actually clicked on it. This may be another bug.)
2. Use the arrow keys to select a cell in the first column
3. Type a letter

Note that the editor appears, but no changes can be made to the cell
If the combo box arrow is selected with the mouse, then changes can be
made with the keyboard.

			if(args.length >0)
			{
				int i=new Integer(args[0]).intValue();
				if(i<lfi.length)
					UIManager.setLookAndFeel(lfi[i].getClassName());

			p.addElement("A");
			for(int j=1; j<5; j++)
			{
				p.addElement("Cell "+i+", "+j);
			}
			data.addElement(p);
		}
		DefaultTableModel dt=new DefaultTableModel(data,columnNames);		
		//create a table
		JTable jt=new JTable(dt);
		jt.setSize(640,480);
		jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
		//create a cell editor
		Vector letters=new Vector(5,1);
		letters.addElement("A");
		letters.addElement("B");
		letters.addElement("C");
		letters.addElement("D");
		letters.addElement("E");
		JComboBox jb=new JComboBox(letters);
		jb.setLightWeightPopupEnabled(true);
		jb.setEnabled(true);
		jb.setEditable(true);
		DefaultCellEditor dce=new DefaultCellEditor(jb);
		//set the cell editor for the column
		TableColumn tc = jt.getColumn(jt.getColumnName(0));
		tc.setCellEditor(dce);
		
		jf.getContentPane().add(jt);
