Invalid Argument error in IE7

[Kaviurs]

All,

I have a very simple Javascript function for opening a popup window, however it fails in IE7 with an "Invalid Argument" error. It works fine in IE6, Opera and Firefox 2.0.

The code is as follows:

Code:
function Validate() {
window.open("LoginWait.stm %LI"+SmtSysToBase64("?Username="+document.Form.Use rname.value+"&Password="+document.Form.Password.va lue+"&RNum="+(new Date()).getTime()), "_top");

}

The error line and character of the error is always character 2 of the line "window.open" appears on in the code.

Any one help to solve this Issue in IE7.

Thanks,
Kaviurs

Find a JavaScript Forum, this is a Java Forum. Java != JavaScript.
