Application crash after open and close PDF rapidly

Hi,
I created application on Windows Phone 8 by using RadaeePDF. After I open and close PDF file rapidly,
application is closed automatically. Debugger doesn't stop. No break point is hit. But I got this message on Output Windows in Visual Studio 2012 which said:

The program '[3488] TaskHost.exe' has exited with code -1073740940 (0xc0000374).

I tried to google about this exit code, but no luck. Could you please help me with this?

P.S. The project, which contain part of PDF viewer in the application, cannot be attached because it's too big (only 1.1 MB ). Can I send the sample project via email?

P.S.2 Sometimes, it shows this message:

The program '[2888] TaskHost.exe' has exited with code -1073741819 (0xc0000005) 'Access violation'.

do you invoked PDFView.vClose()?
mostly need:

Sorry for late reply.
Yes. Those two lines are included.
We found it later that no need to do it rapidly, sometimes it crashes since the first time PDF viewer is closed.

seems some variable like stream, not set to null, and in not check null when NavigateTo.

Hi,

This problem is caused by that some streams are not released when closing the document. We have released a new update for Windows Phone demo. Please download and investigate RadaeePDFPage class for solution. Thank you.
