When I try to open some PDFs, such as uscis.gov/files/form/n-400.pdf with OS X Preview, I get the error message:
If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document.
You can upgrade to the latest version of Adobe Reader for Windows®, Mac, or Linux® by visiting http://www.adobe.com/go/reader_download.

Apple presents Preview as being a better substitute for Adobe Reader, but in this case it does not work at all. (I think this may relate to PDFs with entry fields in them.)
If I set the documents having this problem to be opened with Adobe Reader instead of Preview, the next time I save them from Adobe Reader, they are reset to open with Preview again.
I thus have to always do Open with… for them, or else set all my PDF documents to be opened with Adobe Reader.
Can anyone offer any workarounds for problem (A) or (B)?
Does anyone know Apple's position on problem (A)? Will they eventually fix Preview so that it opens PDF documents such as the one above, or will Preview only ever work on a sub-set of PDF documents?
If Adobe is refusing to provide Apple the information needed to open certain types of PDF documents, does anyone know Adobe's position on this?
