Disconnect causes system freeze

[callanbrown]

Hello, I'm running SSHeven on a Macintosh Color Classic II with System 7.5.3.

Connecting works great to Windows 11 openssh server. However when I click File -> Disconnect, I see this error:

channel read error: LIBSSH2_ERROR_SOCKET_RECV

And the Mac locks up (except for mouse movement). I can see continuing Ethernet activity when this happens.

I should mention I can force quit the application with command+option+esc.
