No problem - sorry I didn't make the relationship between the PIF and the DOS executable clearer. It's about time I got around to releasing a new version which uses my CLSHEAP stuff to make more of the CreateProcess() API call easily accessible, and this time, I'll try to do more than just comment the code...
