SYMPTOMS

When you host the WebBrowser control, all navigation can occur in the hosting application. The following Microsoft Knowledge Base article describes this functionality:

However, when the NewWindow event is fired in response to the scripted window.open method that causes navigation to occur in an Internet Explorer window, a 60-second delay occurs before navigation begins. In addition, in Internet Explorer 4.0x, an "Unspecified Error" occurs.
