This is probably a tough one, that's why I'm offering 300 points for it.
Here's the deal. I have a list of urls which may not be opened. I have to check if a browser with any of the urls on the list is running, if it is, then shut it down.
This has to work with IE, Netscape and preferably Opera.
I know this is possible somehow, I've seen components that can retrieve the URLs of all open browsers, but they are never for free.
