hitTest coordinate dislocation in loaded swf

Hi

The swf (slideshow) has arrows that are activated by hitTests.

When I load the slidewhow swf into another, larger one (e. g. att 100, 100,) a strange thing happens: The hitTest reacts with a mouse displacement of 100, 100, which means that I must move the mouse to a position 100 pixels down and 100 pixels to the right of my arrow to get the mouseOver reaction.

I have tried all the varieties of localToGlobal and globalToLocal that I can think of, but nothing helps.

Does anybody know why this is and how to fix it?
