My desktop would not run the merge function of the companion software, but but my laptop would. Both ran XP. So I would have to connect my DR1000 to laptop to merge scribbles to or with a PDF file. Marcx added a function to his port of Xournal that merges scribbles to a pdf file. He has a version, I think it is up to 9, that runs on 1.7.1. I never needed the companion pc software after that. The link to Xournal is on this forum.
