Farg

hi, i have problem with tabs(hidden\visible) and miscalculation delta time when i back to my hidden tab, example: i have some object near top my display, this object duration to bottom drop = 10ms, when i started animation i fast change tab in my browser and wait 5 sec for see my object at half display when i back to my hidden tab, BUT i see my object remained at top. How i can decide this problem ? p.s. when i make tween i set useFrame:false, but this not helped for me p.s.s. sorry for my engl
