Null Exception after upgrading to dll 2.5.8.0

Hi there,

It looks like there may be a bug in the 2.5.8.0 dll. A Null Reference Exception is thrown.

EventType clr20r3, P1 myapp.exe, P2 1.0.0.0, P3 49749486, P4 alt.sms.smppclient, P5 2.5.8.0, P6 4944c955, P7 10e, P8 3b, P9 system.nullreferenceexception, P10 NIL.

I think it might be the disconnect method (ALT.SMS.SmppClient.Disconnect).

Do you have a new version please?

Could you describe steps to reproduce this exception?

It's tricky because it doesn't happen synchronously.

"Object reference not set to an instance of an object."
