You got me in good mood so here's an example covering both the Timer and onEnterFrame timing techniques: http://www.kemelyon.com/timing_example/ (right click to view source). Near the end of making you the example I figured out what was wrong in your code. Really simple, so simple I often forget it. STOPPING THE TIMER! :) imagine you set the timer to trigger every 3 seconds; after one second you close the alert; after half a second you open the alert again. After half a second the Timer would trigger and your new born alert would be closed. Tell me if this helped, Frederico Garcia
