I have had been running a FTP app for several weeks, incorporating the SecureSocket class. Everything has been dandy until yesterday when I started to get repeated exceptions on the Socket.Shutdown() call. The exception is as follows:
Org.Mentalis.Security.Ssl.Shared.SslException: An exception occurred ---> System.ObjectDisposedException: Cannot access a disposed object named "Org.Mentalis.Security.Cryptography.HMAC".
Object name: "Org.Mentalis.Security.Cryptography.HMAC".

I downloaded and installed the latest assembly to no avail. Any suggestions would be greatky appreciated, any requests for further info will be met as best as my ability will allow.
