I'm stuck.  I'm trying to write a program that sends output to my
postscript printer, but some bug (I'm beginning to think it's not
in my code) causes the program to bomb with *either* "Unrecoverable
Error" or "System Error/Cannot read Device AUX".  The latter is
especially weird, since I don't try to do anything with AUX, and
especially annoying since both the "Cancel" and "Retry" buttons
do the same thing: redraw the same box.  I must then reboot.

So I get the printer params ("PostScript Printer,PSCRIPT.DRV,LPT1:"),
and call CreateDC.  It hands me back a non-NULL display context, and
seems fine.  But when I call Escape(hPr, STARTDOC, 3, "hi", NULL), it
never returns: the print spooler icon appears, my hard drive chugs,
and then I (randomly) get one of the two errors above.  Funny thing is,
it used to work fine.  I made some seemingly unrelated changes to the
program and all the sudden things went wonky.  I'm not out of disk
space, and I'm running only small, standard applications on 2 Meg
of memory in Protected mode.  Any ideas?  I'm desperate.
