Hiding a custom context menu

I've created a pretty sweet right-click context menu to give my intranet
application more usability and functionality.

Everything works sweet and I've styled it to look exactly like a normal
windows menu.

Only behaviour problems which I can't duplicate as yet:

1) if the user clicks on the address bar or a toolbar at the top of the
browser the context menu doesn't hide as it normally would

2) if the window loses focus the context menu doesn't disappeat as it
normally would


I've tried the following for the 2nd one:
	window.onblur = function ()
{document.getElementById('context').style.display='none';};


But it doesn't hide the menu until focus is given back to the window.


How can I achieve both of these aims in IE6?

cheers
