The 2nd option didnt move the tracking graphics for me and the first option produced the same results: updateComplete placement was lagged behind where the debug button places it.
Here is the traceoutput if you cant run it, my notes in ** The x,y values is where I trace the variable p which is generated by the same localToGlobal function ** movie done loading ** update green (x=200, y=200) ** next i scroll the container ** update green (x=200, y=200) update green (x=193, y=200) update green (x=188, y=200) ** now I click the debug button a few seconds later and do not touch anything else ** debug blue (x=181, y=200) ** in this case updateComplete was 7 pixels off where the object stopped actually scrolling ** On Nov 7, 2007 9:49 PM, Alex Harui <[EMAIL PROTECTED]> wrote: > > I didn't run it, but I think you're off a level.
