Windows 7, PPTP VPN, and BSOD

I've been plagued by a Blue Screen of Death (BSOD) issue with Windows 7 (32 and 64 bit) that would occur immediately after disconnecting the built in Microsoft VPN client (that uses PPTP) when connected to a corporate network.  This is the virtual network connecting that you configure in Windows 7 to "Connect to my Workplace".

Turns out the problem was due to an installation of Shrew Soft's free open source VPN client which I need to connect to other VPN's that I use.  On August 17th, 2010 Shrew Soft released a new version, 2.1.6 of their VPN client which FIXES this problem.  If you are using Shrew's VPN Client, you should consider upgrading if you are experiencing this problem.

And, while I am on the topic, Shrew 2.1.6 runs on Windows 7 64-bit very nicely.  I have had no trouble exporting the Cisco VPN Client configuration and then importing into Shrew Net's client and having it work brilliantly to connect to VPN's that use the Cisco VPN Client.  This is important to mention as currently Cisco offers no 64-bit compatible VPN client.
