Stop reader from launching when I create a PDF with PDFWriter

Question

I've been using PDFWriter from an old (licensed) version of Adobe 4.0 in conjunction with AutoCAD and other sotware for several years (the full version is still installed on my machine), but yesterday afternoon, every time I created a PDF using it (as a printer device), Adobe Reader X started launching automatically with the created file in it and slowing down whatever application I was "printing" from (even just printing a Test Page from the properties dialogue box accessed from the printer window).  Thinking it was the result of an automatic update, I uninstalled that version and installed an older version of Adobe Reader (9.5.x), but the result is still the same.  I'm unable to locate any stand alone monitor that might've installed itself in conjunction with version X (or an update), and I cannot find any settings in the PDFWriter properties, nor in version 4.0 of Adobe or the version of Reader I'm running.  I could not find any startup items I could identify as Adobe-related.
Does anybody know how to disable this feature or turn off what I'm calling a PDF Monitor?

Answer 1

Actually, I went back to the help file for the full version of Acrobat I'm using and found out there's a checkbox at the bottom of the Save As dialogue box that pops up when sending the output through PDFWriter.  Somehow it had gotten checked, and since I'd never NEEDED that feature, I never paid any attention to it LOL.   Thanks anyway.  I thought there might've been a monitor installed with a Reader update that had Explorer integration and watched for creation of a certain file type (PDF in this case) since it started so out-of-the-blue.
Thanks
