MORE HELP with: open printing for pdf... SOLVED

Hello again!

In case you were following along, I finally figured this out...  In an attempt to deliver my application as easily as possible, I have my customers download only the exe from my site -- just this one file.  All extra files (extra stacks, images, dlls, etc.) are the downloaded by the exe at runtime.  Works perfectly!   In this case however, there was a problem downloading the "revpdfprinter.dll" file.  The file was being created, but it was 0 bytes.  So, when the app checked to see if the file was there, it was -- but it was invalid.  So, I put in an extra check to verify that the size of the dll is exactly 753664 bytes.  If it's not we download it again.  If it fails again, then I point them to a web page that has the file and instructions.  Problem solved.

Time for a fresh cup of coffee.

If I "open printing to pdf" and then run multiple "print card" commands, each print comes out as a separate document and I am asked to select a location to save the output for each page.   I haven't issues a "close printing" command yet, but it's still outputting separate PDFs.  It works fine in the IDE, it works fine in the Mac Standalone, but I get this odd behavior on with the Windows standalone.
>> One note...   I "open printing to pdf" in stack A.  Then, I open stack B and do the "print card" commands.  Then, I close stack B and stack A issues the "close printing" command.  I then repeat as needed.   I don't think this matters as it works in the IDE and on the Mac.
