Thanks works great - you confused me with the semi-colons :-) Thanks
Bruce too - your posts
re:sys.argv were useful in looking at this.
I'll raise a feature request of some sort. Is PYC ever likely to
become part of the standard install?
In case it is of use to anyone, I've put my modified PYC on my
skydrive. Also has a modification for STA as I use the webcontrol in

In theory we can burn a reference from your DLL into your EXE and have the CLR load the assembly and it should be able to pick it up w/o changing the CWD. The problem seems to be that we end up with "DIE.EXE" and "DIE.DLL" and it would appear the CLR always loads DIE.EXE and then it doesn't find the types in DIE.DLL. Presumably if we named them different this would work. Maybe we should enable naming them differently or maybe we should enable generating just one EXE instead of the wrapper EXE.
