Application Hang with Win 7 and 2008 R2 Web App

Hello,

Using this equipment:

Client: Win 7 Enterprise + SP1 and mstsc.exe 6.3.9600 (RDP 8.1 supported)

Server: Server 2008 R2 Remote Web App

Network Connection: Juniper Junos VPN to corporate network

Application: .NET Windows Forms 4.0 - No hangs on normal Remote Desktop Connections

We can connect to the Remote Web App and the Application appears.  After about 4+ minutes using the application, it hangs (does not respond to any mouse clicks).   The process must be killed with Task Manager.  We can connect again and the Application works for about 4+ minutes.

Here is the Client side error:

Here is the debug exception message:

Unhandled exception at 0x000007FEB0F8BA0A (mstscax.dll) in mstsc.exe: 0xC0000005: Access violation reading location 0x0000000000000780.

Here is the Windows application event log entry:
