Animated gif moving to fast

Question

I am trying to display an animated gif in a JLabel. My problem is that for some reason the animated gif speeds through the frames, instead of moving at the speed it was created at. Any idea what might be causing it.
Below is the code I'm using to display the animated gif.
import java.awt.*;
import javax.swing.*;
import javax.swing.JDialog;
import java.io.*;
public class loadingScreen extends JDialog
     private JLabel loadingLabel;
     ImageIcon loadIcon = new ImageIcon("images/animated_loading.gif");
    This function makes the loadingScreen a dialog box which, when
    opened, limits the user to be only able to use this window until
    they close it.
     public boolean startLoadingScreen()
          Window owner = (Window) getParent();
          Dimension d = getSize();
          Rectangle r = owner.getBounds();
          int x = r.x + r.width/2;
          int y = r.y + r.height/2;
          setBounds(x, y, d.width, d.height);
          getCenter();
          setVisible(true);
          return true;
    This function is called by an outside program. It takes in the owner
    frame information. It takes in a string that will be the title of
    the dialog box.
     public loadingScreen(Frame owner,String title,boolean modality)     
          super(owner, title, modality);          
          displayWindow();
    This function makes the gui for the window
     public void displayWindow()
          setResizable(false);
          Box groupBox = Box.createVerticalBox();
          loadingLabel = new JLabel(loadIcon);
          groupBox.add(loadingLabel);
          Container dialogPane = getContentPane();
          dialogPane.setLayout( new FlowLayout() );
          dialogPane.add(groupBox);
          pack();
     private void getCenter()
          Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
          Rectangle frame = getBounds();
          setLocation((screen.width - frame.width)/2,(screen.height - frame.height)/2);
}

Thanks for the help. Once I editied the gif file everything worked fine. As a side note, I used Gimp to edit the file and when I tried saving it had a funny message. "Delay inserted to prevent evil CPU-sucking anim."
Thanks for the help.
