[jQuery] Having trouble with contextMenu plugin in a frame

Hi,
I'm using the context menu plugin from here --
http://www.trendskitchens.co.nz/jquery/contextmenu/. The problem I'm
having is that when the functionality is in a frame, right clicking
sometimes cuts off part of the menu -- http://screencast.com/t/Z9lGuq5X.
I'm wondering if you know of a way to position the menu such that it's
fully visible.
Thanks for any help, - Dave
