Consider the following scenario:
- You have a smart card that is installed on a computer that is running Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2.
- You run a program that requires you to use the smart card.
- The program crashes.
- You run another program that requires you to use the smart card.
In this scenario, all programs that try to use the smart card do not successfully connect to the smart card. When this situation occurs, the process that connects to the smart card hangs.
