Under Win XP they open DiagRA just fine; under Win 7 I'm getting:
OSError: [Errno 22] Invalid argument
Needless to say, I checked the path under Win 7; it is correct.
As you can see, I tried the same lines with notepad, just in case;
same result. Works fine under XP, IOError under Win 7.
So I'm pretty sure it's some kind of Win 7 access rights issue... Can
anybody point me to a concise overview of the issues involved, and
maybe even the known solutions? Again, it's os.spawnl in Python 2.2,
under Win 7.
