Context in depth

Hi,

I am overriding the browsers context menu with one of my own. However, I am not clear on how to immitate some of its functionality. One in particular is the modal behaviour of the menu. When you right click the document, the context menu pops up. When this happens, no other events fire on the document. For example, I have a mouseover event which calls an alert on my table. But, if the context menu is showing, this event does not fire.

How can I do the same thing with my context menu?
