Hi,

I've come upon a page that causes the EO.WebBrowser to crash.

I am using EO.WebBrowser in a vb.net wpf application, and when i navigate to this page: http://jyllands-posten.dk/ i get a System.NullReferenceException. Caused by the WebBrowser adding a cookie.

Code: Visual Basic.NET

Copy

A first chance exception of type 'System.NullReferenceException' occurred in EO.WebBrowser.dll

I can reproduce the problem in the provided sample: "TabbedBrowser".

The full trace is here (excuse the Danish):

Code: HTML/ASPX

Copy
