Just to confirm: mintty does no such thing, and I don't know what it could be doing. All it sees is a file descriptor for reading and writing the pty device, so it doesn't even know what sort of process it's talking to. I think any solution to this issue should be done as a standalone wrapper that needs to be invoked explicitly, at least initially. If it proved itself, it would be worth considering to invoke it automatically from the Cygwin DLL when a Windows program is spawned. Andy
