Browser, not engine ---> Event Handling
Here is the <textarea> involved:

<textarea name="message" rows="5" cols="40" align="middle" wrap="soft"           
          onfocus="count_text(this.value)" onchange="count_text2(this.form)"           
          onblur="timer_stop()">
</textarea>


where we have:


//-------------------------------------------------------------
// The actual subroutine that starts the counter.  		        
//-------------------------------------------------------------
function timer_start() {    									    
  running = true  
  now = new Date()        							        	    
  now = now.getTime()  
									            
  if (is_message){   									                
    endTime = now + (counter_speed_short * 0.1 * 1)  
  }
  else {  									                
    endTime = now + (autotab_speed_short * 0.1 * 1)  								          
  }
									          
  show_timer()
}
        
				        				
//-------------------------------------------------------------
//The actual subroutine that stops the counter.  			        
//-------------------------------------------------------------
function timer_stop() {        
  clearTimeout(timerID)   
  running = false
}

Confirming bug with Mozilla trunk binary 20020520xx on WinNT.
In IE6, I can type something in the textarea and then switch
focus to another input, for example, "Character Count"

Whereas in Mozilla, focus keeps returning to the textarea.
James, is that what you meant?

Yes.  This is exactly what's happening.  The onblur event function should be
called to clear the timer.  If the timer is allowed to expire then the focus is
placed back in the message textarea.  This works in Netscape 4.79 as well as IE6.

I'm seeing exponential growth in number of timers.... Basically, the onchange is
triggering code on the page that seems to set a new timer without clearing the
old one, and then timer_stop can never get rid of the old timer.

The "message" textarea has onfocus="count_text(this.value)"
the code in show_timer() that eventually does something (when the timeout is
reached) effectively does this:

document.Form1.counter.focus();  // blurs textarea                             
                                                            
document.Form1.message.focus();  // focuses textarea ==> new timeout
count_text(document.Form1.message.value);  // another timeout

hence exponential growth.  I really have no idea why it's blurring/focusing the
textarea.  It's in a non-MS UA if block.
