Running TCMD 12.00.25 x64 on Win7 x64.

When I telnet to a host, it connects, and then return to the telnet prompt by pressing CTRL+[, TCMD will crash on the next keypress.

This does not happen with cmd.exe.

Just the standard Windows telnet client.

BTW, I meant CTRL+] above, not the other bracket.

I don't a tcmd.gpf on my system, but here is some info from the Windows error dialog:

The problem does not happen with cmd.exe or tcc.exe (when run alone). It only happens with tcmd.exe. I don't think I've ever seen connhost crash except when running tcmd.exe.

And yet, the crash is in conhost, not TCMD ... :-)

The bug in conhost has to do with changing console buffers in hidden
consoles. Since neither TCC nor CMD is hidden, you're not likely to see it
surface there!

Fortunately, only telnet and one or two other oddball apps try to do this.
