dialog is being clipped in iframe

I'm creating a flex application that has an iframe over it with fckeditor. I have everything working great so far but when I click on a button that opens a dialog, part of the dialog will be clipped off. It's because it is opening the dialog in the iframe but centering it to the screen width and height. I'm using version 2.6.4.1.

Is there a way to open the dialog outside the iframe at my top level?

Or can I change the position of where the dialog opens relative to the iframe and not the screen size?

Thanks
Jeff
