The code that you posted looks OK (just keep in mind that you need to provide the full Url as the parameter, i.e. openYahooWin('http://
www.yahoo.com') or you would get a "resource cannot be found" error because the browser will look for a file called www.yahoo.com in your project's folder.
At this point I cannot tell what the reason for the problem might be, but if you send me a sample application, I will check it and get back to you right away.
