spawnl issues with Win 7 access rights

[Propad]

Hello Tim,
thanx for the fast answer. Sorry to hear there are such issues.
I'm obviously not free to choose my version of Python, or I'would be
using the latest'n'greatest. It's more like this: I'm obliged to use
the version delivered with dSpace tools (which is HiL - ECU-testing
software for the automotive and aerospace industries).
I'just might be able to use 2.5, which dSpace delivered  2-3 years
ago; but I'm not sure of that, and not sure it would help in any way.
So some solution without tweaking the code or anything would be realy
nice. I can't imagine anything of such importance was not tested at
all during the beta phase - so it could be the tests were not run with
such a tricky configuration of windows.

Any hints are appreciated!

Cheers,
Nenad
