Thanks for the consideration, Nick. I don't know why everyone says you're so mean.

I extracted the pdftoppm program from your link, set it up as best I can, changed one default parameter - so it would create a pgm file instead of a ppm file - and gave it a go. That might be the source of subsequent problems with pi-exe, but it didn't prevent pdftoppm from doing it's thing.

The program created 52 pgm files from the pdf I'm using for testing purposes. While that's a lot, it's the one type of pdf I know I'm gonna need to convert monthly, so I figured I'd see what happened.

Took one of those 52 files, and did the "pi X.pgm Y" thing, which produced the following messages:

C:\Documents and Settings\Rick\My Documents\Unzipped\pi-exe\pi> pi CT0408-000001 .pgm ct0408-01

The stackdump file look slike this:

As far as I know, I'm not using the 0.2 version, that you cautioned about (though who knows? Anything's possible wit Da Idiot in Da House.)

Looking forward to your reply. Thank you!
