One trick to use setInterval is to clear the interval ID every time you
establish one regardless if the existence of the interval ID. This will
make sure you still controlling the interval. If you establish
setInterval more than one time to the sample Interval ID, the previous
established interval is still running and you hardly clear it.
Following codes only make minor change to yours. Whenever you want to
reset your watch, you only need to call doStopwatch() function at
anytime like what I did to your imaginary buildQuestion() function. But
I am not sure what you try to do with this IF statement " if ( id >=
questions.length ) " as it seems to create infinity looping when id >=
question.length, unless you have simplified your function for this post
to focus on setInterval thingies..
function doStopwatch() {
// 1second = 1000ms
clearInterval( _root.stopwatchIntervalId ); // **********
_root.stopwatchIntervalId = setInterval( _root.stopwatchComplete,
3000 );
}
function stopwatchComplete() {
clearInterval( _root.stopwatchIntervalId );
// trigger the question completed method
_root.questionComplete( _root.question.id, _root.question.type );
}
function questionComplete( questionId, questionType ) {
if ( id >= questions.length ) {
// out of questions
_root.stopwatchComplete();
} else {
// next quesiton
buildQuestion( questionId + 1 );
}
}
function buildQuestion( new_questionId ){
doStopWatch(); // **********
// ... Your build question function code
}
If you need IDLE handling sample, I can sen you one

Subject: Re: [Flashcoders] setInterval() and the trouble
Hi Liam,
First of all I always have had trouble with those methods, never got it
right. Always failed, I don't they dont like!

Well, I happen to have a resource xml file which get loaded prioer of
each group of questions, once this group is readed a
method in the root timeline gets triggered which will determine what to
do. This method will also trigger the method buildQuestion() when
required, this method will create a new instance of
"question"-movieclip. After this part is done the function doStopwatch()
is called:
function doStopwatch() {
// 1second = 1000ms
_root.stopwatchIntervalId = setInterval( _root.stopwatchComplete,
3000 );
}
function stopwatchComplete() {
clearInterval( _root.stopwatchIntervalId );
// trigger the question completed method
_root.questionComplete( _root.question.id, _root.question.type ); }
function questionComplete( questionId, questionType ) {
if ( id >= questions.length ) {
// out of questions
_root.stopwatchComplete();
} else {
// next quesiton
buildQuestion( questionId + 1 );
}
}
IF you have a better solution please let me know! I feel so stupid that
I don't get thing timer stuff working.
Yours,
