PythonNet and PythonService.exe

Well folks, just a week ago i was happy to discover PythonNet. Unfortunately it doesn't work
when its running under PythonService.exe which is the most natural way to run python as services as coded by Mark.

It runs fine in 32 bit Os, but the moment i tried it on Windows 2008 64 bit, it just terminated unexpectedly. The problem lies with the statement "import clr". i have exhausted all ways to get this working without writing my own pythonservice replacement and i conclude that its not usable
except for writing standalone tools that client need to manually click on or run by the scheduler.

Running the same program on a 64 bit OS manually works!, so the problem could lie in the
way python.runtime.dll is loaded by pythonservice.exe on "import clr".

Meanwhile, life goes on :-(, its back to .COM in .NET whenever we need Python to use certain calls to an existing .NET library.
