This is, I belive, in the "common questions" posting.
If you set your process's pr_WindowPtr to -1, Dos errors will not put up
a requester, but simply return an error code.  By default it's 0, meaning
workbench screen, but you can also point it to a window, and error requesters
will pop up in that window's screen.
