ckeditor context menu - trying to fix reposition

hi all,

i have a context menu http://abeautifulsite.net/2008/09/jquer ... nu-plugin/
i made a change to the context js file, i modified it so you could right click anywhere on the page rather than in a specific area

much like the ckeditor one in the editor, but i have 1 problem

when you right click towards the end of the browser, it doesn't reposition itself back inside the browser

it pushes the page side or down(if there aren't enough room for the context menu to show, or down)

i have tried putting in the fix as posted here http://plugins.jquery.com/node/4263 but it still doesn't fix it

i've attached a sample what i have so far

just try and right click to the edge right of the browser, you'll see it pushes the page to the side (or down if you right click near the bottom of the page)
