The peculiar problem is that IF i include the System.out.print(""); line in the method, the program works FINE, if however I delete the System.out.print(""); methods or REM it out, the program doesn't count time?  How Could that one line which does NOTHING cause the entire program to function correctly?

Hmm, I just wrapped your code in a *simple* test class and ran it, it 
produces output with or without the System.out, I think you should be 
looking elsewhere.

package com.foo;

public class TimerTest extends Thread{
	
	int hrs, min, sec, secCount;
	boolean debug = true;
	boolean paused = false;
	
	public void run(){
         long timeStamp = System.currentTimeMillis();

         while(true){
             if(timeStamp + 1000 <= System.currentTimeMillis()){
                 timeStamp = System.currentTimeMillis();

                 //System.out.print("");
                 if(this.paused==false){
                     this.secCount++;

                     this.hrs = (int)this.secCount / 3600;
                     this.min = (int)(((int)(this.secCount % 3600))/60);
                     this.sec = (int)this.secCount % 60;

                     if(this.debug) System.out.println("Timer: 
"+this.hrs+":"+this.min+":"+this.sec);
                 }
             }
         }
     }
	
	public static void main(String[] args){
		new TimerTest().start();
	}

}

//output

Timer: 0:0:1
Timer: 0:0:2
Timer: 0:0:3
Timer: 0:0:4
Timer: 0:0:5
Timer: 0:0:6
Timer: 0:0:7
... etc
