Debug with big Vectors in AS3

I am using Flash CS5 and only actionscript. I mainly do signal processing with an input which is a Vector., process it and then end up with a new Vector.. I would like to debug my program with the debug in Flash but when I put a breakpoint and try to see the value of Vector., it takes 5min to load and Flash is frozen (my Vector contains a lot of elements, a开发者_如何转开发round 1million) which is not easy at all for debugging. Is there a good way to do it ?

As an image is always helpful, clicking on the red arrow frozes Flash for a long time and sometimes make it crash : (I sometimes have after the error when I want to debug again : "You can not debug this SWF because it does not contain Actionscript" and I need to restart Flash CS 5, quite annoying).
