showInputDialog freezes other windows

Im using several showInputDialogs in a program. When one of these input pops up it freezes all the other windows in the background until it has recieved an input, is there a way to make it not freeze the other windows?

If by "freeze" you mean that the user cannot access the other windows, then the key is to make the new dialog a non-modal dialog. You can extract the JDialog from the JOptionPane and then elect to display it in a non-modal way. The JOptionPane API will show you how. Search for the section titled "Direct Use:"

Playing with code....

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;

import javax.swing.*;

public class Foo {

   public static void main(String[] args) {
      final JTextField textfield = new JTextField(10);
      textfield.setFocusable(false);
      final JPanel panel = new JPanel();
      panel.add(textfield);

      panel.add(new JButton(new AbstractAction("Push Me") {

         private JOptionPane optionPane;
         private JDialog dialog;
         private JTextField optionTextField = new JTextField(10);

         @Override
         public void actionPerformed(ActionEvent arg0) {
            if (dialog == null) {
               JPanel optionPanel = new JPanel(new BorderLayout());
               optionPanel.add(new JLabel("Enter some stuff"),
                     BorderLayout.PAGE_START);
               optionPanel.add(optionTextField, BorderLayout.CENTER);
               optionPane = new JOptionPane(optionPanel,
                     JOptionPane.QUESTION_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
               dialog = optionPane.createDialog(panel, "Get More Info");
               dialog.setModal(false);
               dialog.addComponentListener(new ComponentAdapter() {
                  @Override
                  public void componentHidden(ComponentEvent arg0) {
                     Integer value = (Integer) optionPane.getValue();
                     if (value == null) {
                        return;
                     }
                     if (value == JOptionPane.OK_OPTION) {
                        textfield.setText(optionTextField.getText());
                     }
                  }
               });
            }
            dialog.setVisible(true);
         }
      }));

      JFrame frame = new JFrame("Frame");
      frame.add(panel);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.pack();
      frame.setLocationRelativeTo(null);
      frame.setVisible(true);
   }
}

Use a non-modal JDialog instead. See How to Use Modality in Dialogs for details.
