David,

  I've attached a class which runs the lcd0.97 reconstruction with
fitting turned OFF. It has a line

	// Turn off track fitting
	addReconTrks.setNoFitting();

after creating the AddReconTrks process.

To replace the standard version in your analysis do the following

  ...
  // import hep.lcd.recon.tracking.*;
  import hep.lcd.util.driver.*;
  ...

  public class LCDDriver extends Driver
  {
    public LCDTrackDriver()
    {
      add(new TrackReco()); 
      add(new TrackAnalyzer());
    }
  }

That is, this modified version of TrackReco is NOT in the
hep.lcd.recon.tracking package so comment out the import line. Put
TrackReco.java and TrackReco.class in your main jas directory along with
your LCDDriver.

Please let me know if you have any problems.
Mike
