<div class="">in Google Chrome. It looked perfect in Chrome. Then I downloaded it to my desktop. The icon on my desktop shows an image of a page with writing on it, but, when I open the document with Skim, it contains nothing but 18 blank pages.</div>

<div>This document has a badly constructed Annotation that coves the whole of the 1st page.</div>

<div>In Acrobat, with a Ctr-click on that 1st page, one gets the option to Edit or Delete</div>

<div>The metadata does not report this file as having been created by TeX software.</div>
<div>Maybe it has undergone some post-processing, resulting in Metadata</div>

<div>My conclusion: not an issue regarding LaTeX production of PDFs.</div>

</div>
<div>As for Apple?  </div>
<div>Well it’s a badly formed PDF, which nevertheless has valid content streams. </div>
<div>It becomes a matter of deciding how to handle badly-formed extra layers </div>
<div>— which it probably isn’t going to show anyway.</div>
<div>You want to just ignore the objects, but that is easier said than done, </div>
<div>the correct syntax hasn’t been followed.</div>
