I've read a bunch of posts and the MSFT KB article which say you can't
catch the javascript call to showModelessDialog() in order to prevent
the dialog from appearing.

However, IE7 seems to be able to block popups from websites which use
showModelessDialog() without the user clicking on anything.

I believe NewWindow3 event, new in IE7, does report such dialogs.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

Nope, it doesn't :(- Hide quoted text -

Igor - I've actually found one thing which will stop it --
implementing IInternetSecurityManager::ProcessUrlAction(), and
returning URLPOLICY_DISALLOW if the action is URLACTION_SCRIPT_RUN.

The problem is then how to determine which scripts are good and which
are evil? How can you know that a script is about to launch a popup
versus just a script which may read cookies or similar? Even if I
only allow scripts to execute after a click event, I may be disabling
useful scripts from running.

Any ideas?
