Answer 1

This turned out to be either
var myFunc:Function=someFunctionFromOurCode;
myFunc.apply(null,args);
//OR
myFunc.call(null);
changing the nulls (thisObj params) to something more appropriate killed the bug.
The reason I was setting the thisObj to null is because none of the functions getting called required a "this" scope
