BUG: window.open Causes Delay in NewWindow Event

• Microsoft Internet Explorer (Programming) versions 4.0, 4.01, 4.01sp1, 5.0dp1

SYMPTOMS

When hosting the WebBrowser control, it is possible to have all navigation occur in the hosting application. This is described in Knowledge Base article number Q185538 "HOWTO: Cause Navigation to Occur in Same WebBrowser Window."

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

RESOLUTION

The only known workaround is to create a new instance of the hosting application for the new window. This is described in the following article in the Microsoft Knowledge Base:

Q184876 HOWTO: Use the WebBrowser Control NewWindow2 Event.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
