Printer Config with custom page size...

I create a printer configuration (PC3) file for 24"x48" sheet with the PDFCreator driver. To define the sheet I set the paper size to "Postscript Custom Page Size"

This shows up as a media size "User32767" in the printer configuration editor dialog. See:

When I go through the page setup dialog for my layout and choose my PDF24x48.pc3 the default page is defaulting to Letter.

I open the PC3 file in the config editor again and it shows the media size is set to "User257":

This relates to an additional problem when I open older files saved with page setups based on User32767 media size I always have to select the correct page size.

Thanks!
