Weird problem. I would just go through your code and how you put it into your web page, you are doing something very wrong if you have this problem.
There is no real answer without and fla file to show us and more info on the problem.
I would just look through the lines of code and check to find the obvious problems and how your method is suppose to work and try other ways.
