I have CefSharp-master project with which is Built on Chromium- 31.0.1650.57. All is working fine and perfect, but when I click on link to load/view PDF file on an website and popup get loaded and after some time I got dialog box saying **"CefSharp.BrowserSubprocess.exe has stopped working."** and oped popup window become black. Below is what I found in windows event viewer..

```
Application: CefSharp.BrowserSubprocess.exe

Description: The process was terminated due to an unhandled exception.
Exception Info: System.AccessViolationException
Stack:

   at CefSharp.CefAppWrapper.Run(System.String[])
