	JComboBox combo2= null;
	JButton b = new JButton("Press Me");
	ScrollBarVisibleBug(){
		frame = new JFrame();
		frame.setLayout(new java.awt.FlowLayout());

N/A

Simple fix, combo had state PRESSED not PRESSED+DISABLED when it was clicked on and disabled. Also combo arrow button could enter pressed state when combo was dissabled.
