Hi all, We're attempting to begin using Acad2004 (on WinXP), and I'm having trouble with something that has never given me a problem under Acad 2000. We plot to a networked HP1050c with a 36" roll loaded. We use all 5 custom sizes to handle our particular sheet sizes, and then go into "Modify Standard Paper Sizes (Printable Area)" to reduce the margins on all sides to zero. Like I said, this works fine in Acad2000. In 2004, the first time I set the printable area (before the PMP file has been created), it prompts for the margins, then the filename, and it saves correctly. After that, no matter what sheet size I select to modify, it prompts for the margins, seems to proceed normally, and allows me to finish/exit. But if I recheck the sheet size I just changed, it's already back to its original margins. It's not a permission issue, as the file is stored locally and I have full administrative rights to the PC. I can't find anything on Autodesk's support knowledgebase, nor have I seen anything like this listed in this newsgroup. If anyone has any suggestions (hopefully short of creating multiple PC3/PMP combos for each sheet size and orientation), I would appreciate it. Thanks, Dave
