Problem with mouse events

i have a problem with the mouse event, there are objects on the stage that have both, down and over while down mouse listener functions, the problem is when i click on the object the second time, it doesnt return the object, it returns the stage instead, after a click or two it starts again to capture correctly, and so on.
when it doesnt detect the click on the object, i get the stage!
i attached the file which contains the action script, i removed everything except for the click handling functions and the objects.
please help.
