   But if there weren't any complaints, then we wouldn't know what to fix
<wink>.

   SciTE is the dumbest on your list, not attempting to be a debugger at all
and just executing a Python file in an external process and piping the
output into a window.

   These are fairly easy although chances of a process kill differs between
OS versions.

   What is hard if Python is run out of process is to performing debugging
operations such as single stepping and examining variables.

   Go on, but I bet you'll want a real debugger after a short period and
that is something I'm unlikely to find the time to add to SciTE.

   SciTE gets lots of additions but there is not much quality control so at
any time several of the features are sure to work strangely. Boa is alive
but progressing slowly. PythonWin doesn't see much improvement as Mark is
very busy with a lot of work including Komodo.

   PythonWin could be fairly easily made to have an option to run programs
in another process but not allowing debugging. With open source though, its
a matter of someone being sufficiently motivated (or annoyed) to invest the
effort.
