Window Close?

[Jick]

Is there a way to disable the X button in the upper right hand corner of a window? I'm going to have a pop-up that is activated by a link and I want it so the only way they can close the window is by hitting the close button that I put on the page. I want to disable the X button so they can't just simply hit the X button to close the window. Is this possible?

From time to time I am asked why I disable JavaScript when I browse.

if the window is opened using
window.open

then you can set one of IE specific features

fullscreen=yes

in the window properties this will force the window to take up all the screent area without showing title bar,hence no X buttons,
Mind you this could be more annoying then helping users,therefore I will be very carefull suing something like that..
And personally I don't think MS should have implemented this property for windows..
