My thread is ceated but doesn't have desired effect. Help?

Question

Basically I have a jDesktopPane wiith many jInternalFrames. I need each one to be its own thread so if one locks up the whole program doesn't crash. Right now it all works fine, but if you run a method on a huge file in a jInternalFrame it'll lock the whole program up. Using netbeans I can tell that I am indeed creating a thread. I think. ok here's some code- (yes I know its not the simple, compilable, blah blah blah thing. Its 12 java files, I'm not making an example program)
getCurFrame();
new Thread(SimpleJavaEditor.ifArr[SimpleJavaEditor.curFrame]=new NewJInternalFrame(SimpleJavaEditor.curFrame,jFileChooser1.getSelectedFile())).start();
SimpleJavaEditor.jDesktopPane1.add(SimpleJavaEditor.ifArr[SimpleJavaEditor.curFrame]);
public class NewJInternalFrame extends javax.swing.JInternalFrame implements Runnable, InternalFrameListener, ActionListener, KeyListener, MouseListener {
    @Override
    public void run() {
        initComponents();
        requestFocus();
        jTextPane1.getDocument().addUndoableEditListener(
        new UndoableEditListener() {
          public void undoableEditHappened(UndoableEditEvent e) {
            if(e.getEdit().isSignificant()){
                undoManager.addEdit(e.getEdit());
        jScrollPane1.getVerticalScrollBar().addAdjustmentListener(new java.awt.event.AdjustmentListener() {
            public void adjustmentValueChanged(AdjustmentEvent e) {
                if(jScrollPane1.getVerticalScrollBar().getValue()<=jScrollPane2.getVerticalScrollBar().getValue()){
                   jScrollPane2.getVerticalScrollBar().setValue(jScrollPane1.getVerticalScrollBar().getValue());
                }else{
                   jScrollPane2.getVerticalScrollBar().setValue(jScrollPane2.getVerticalScrollBar().getMaximum());
        jScrollPane2.getVerticalScrollBar().addAdjustmentListener(new java.awt.event.AdjustmentListener() {
            public void adjustmentValueChanged(AdjustmentEvent e) {
                if(jScrollPane2.getVerticalScrollBar().getValue()<=jScrollPane1.getVerticalScrollBar().getValue()){
                   jScrollPane1.getVerticalScrollBar().setValue(jScrollPane2.getVerticalScrollBar().getValue());
                }else{
                   jScrollPane1.getVerticalScrollBar().setValue(jScrollPane1.getVerticalScrollBar().getMaximum());
        FontMetrics fm = jTextPane1.getFontMetrics(jTextPane1.getFont());
        int charWidth = fm.charWidth( 'w' );
        int tabWidth = charWidth * 3;
        TabStop[] tabs = new TabStop[10];
        for (int j=0;j<tabs.length;j++){
            int tab = j + 1;
            tabs[j] = new TabStop(tab*tabWidth);
        TabSet tabSet = new TabSet(tabs);
        SimpleAttributeSet attributes = new SimpleAttributeSet();
        StyleConstants.setTabSet(attributes, tabSet);
        int length = jTextPane1.getDocument().getLength();
        jTextPane1.getStyledDocument().setParagraphAttributes(0, length, attributes, true);
        length = jTextPane2.getDocument().getLength();
        jTextPane2.getStyledDocument().setParagraphAttributes(0, length, attributes, true);
        keyWord();       
    public NewJInternalFrame(int Frame,File fileA) {
        frame=Frame;
        file=fileA;
    }I think that should be enough. Ask if you need more code.
Thanks

And since you aren't making the effort to make an example program, we probably won't go to much effort to help.
That said, I didn't read your code since it wasn't simple or compilable, but it sounds like you need to do your logic on a separate thread. Try looking at SwingWorker.
