SSHClient causes a crash when connecting to an invalid server

My company just upgraded the UltimateTerminal component from version 6.3.60124 to 6.8.4155 and I have discovered a major issue. When using the SSHClient, if you try to connect to a server that either does not exist or does not support SSH, my program now crashes and shuts down. In the old version, an exception was raised that indicated either a timeout or that the target machine actively refused it, which I could simply catch and handle. But the new version just bombs out with no warning. I have seen the same problem with your pre-compiled samples (specifically the SshClient.exe sample), so it's not just my code. I am running Windows 10 with version 4.7.1 of the .NET Framework installed (but my program targets version 4.0). I have tried the samples on a Windows 8 machine and have the same issue. As I mentioned, I have seen this in your sample programs, but as a very simple test, here is a piece of sample code I was using to create the problem. Public Class Form1 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Try Using m_Client = New SshClient m_Client.Connect("192.168.43.44") If (m_Client.IsConnected) Then MsgBox("Connected") Else MsgBox("Not Connected") End If End Using Catch ex As Exception MsgBox(ex.Message) End Try End Sub End Class For the IP Address to connect to, enter an invalid address or an address that does not support SSH. When using the old version, an exception is raised on the Connect call and is shown to the user. But with the current version, the program just shuts down without catching any exceptions. The ConnectAsync method also exhibits the same behavior. You do get a standard Windows "Program has stopped working" message, but that's it. And an error is written to the Windows event log, like so: Faulting application name: SshClient.exe, version: 1.0.0.0, time stamp: 0x592123ad Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc00000fd Fault offset: 0x00007ffd84cbb601 Faulting process id: 0x384 Faulting application start time: 0x01d412dc2a4a183b Faulting application path: D:\Users\dla\Desktop\CompiledSamples\SshClient.exe Faulting module path: unknown Report Id: 4152b46f-498d-4f64-8395-433a381b07d7 Faulting package full name: Faulting package-relative application ID:

We were aware of that issue and have been working on a new version 7.0 that addresses this issue. Regards,
