Thanks. When PDFPen was new, I bought a copy, filled in multiple pages of a corporate tax return using IRS-provided fill-in Acrobat PDFs, and watched in consternation as my work literally just slid off the virtual page.PDFpenPro creates PDF fill-in forms with one click. It includes multiple other capabilities like digitized signatures, OCR conversion of any PDF, and digital signatures.
When I contacted Smile Software, I learned that PDFPen (then) used the same technology as Preview, which continues now to be incompatible with Acrobat fill-in forms, at least per Adobe's site.
Given that my experience is "stale," I'm ambivalent about bringing it forward to today when I've not used PDFPen since.
Perhaps someone who's used PDFPen recently to fill a complex fill-in document created with Adobe's Acrobat can comment?
