Hi!
It works very well, thank you!
Fixed in the CVS version, the next release will allow Ctrl+Z or Ctrl+D
to terminate an input stream. There were also a few additional fixes
around the interact code that I made.
If you want to use these fixes before the next release:

Extract winhugs.exe and replace the existing winhugs.exe in a Sep 2006
installation.
