You're probably using scheduleRepeat. Browsers are strictly single threaded
(some multi-threading Javascript support coming in FF3.1 that I know of).
Anyways your problem is this:
run()
showWindow()
browser keeps generating timer event probably because that comes from the OS
& there's no locking in place
user clicks on button
next event is shown
Instead do this:
timer.schedule(1000);
run() {
showWindow()
timer.schedule(1000);
}
